The integration of photothermal therapy (PTT), photodynamic therapy (PDT), and immunotherapy represents a promising strategy for enhancing anticancer efficacy. However, current approaches often rely on cocktail-based nanoplatforms that load multiple agents, which complicates preparation and raises concerns about stability and potential side effects. Therefore, developing structurally simple, easily synthesized nanomaterials with inherent multifunctionality is highly desirable. In this work, we report the first synthesis of biocompatible heterostructures. The interfacial contact within these heterostructures facilitates efficient charge carrier separation, enabling the simultaneous activation of photothermal conversion and photodynamic functionalities under near-infrared (NIR) irradiation. Beyond these photophysical effects, the obtained Bi₂Se₃@BiSe nanosheets effectively polarize M0 macrophages toward the tumor-suppressive M1 phenotype, a process which in turn promotes robust immunogenic cell death. Collectively, this work establishes Bi₂Se₃@BiSe as a versatile nanoplatform for triple-modal cancer therapy, seamlessly integrating PTT, PDT, and immunotherapy, thus proposing a novel paradigm for developing next-generation combinatory cancer therapeutics.

The treatment of pancreatic cancer has long been a global challenge. Strategies based on mitochondrial Ca2+ overload-related ferroptosis have garnered significant attention. However, the various limitations of current Ca2+ generators make it difficult to maintain an effective concentration of Ca2+ overload. In this study, we developed a nanocomposite material, CaO2@Fe(SS)-MOF@Ce6@PAA (CFMCP), by encapsulating CaO2 nanoparticles (NPs) and the photosensitizer Chlorin e6 (Ce6) within a metal-organic framework (MOF) and further modifying it with polyacrylic acid (PAA). This nanocomposite effectively depletes glutathione (GSH) in tumor tissues, thereby enhancing the efficacy of photodynamic therapy (PDT) and chemodynamic therapy (CDT). Upon co-incubation of CFMCP NPs with SW1990 pancreatic cancer cells, we observed efficient cellular uptake of the nanomaterials. Under the influence of CFMCP NPs, cellular GSH and glutathione peroxidase 4 (GPX4) levels decreased, exacerbating oxidative stress and lipid peroxidation, increasing Fe2+ content, and aggravating mitochondrial damage. Using the mitochondrial Ca2+ uptake inhibitor Ruthenium red, we further confirmed that Ca2+ overload is a critical mechanism by which CFMCP NPs induce ferroptosis in SW1990 cells. In vivo studies demonstrated that CFMCP NPs exhibit excellent biocompatibility, significantly inhibit tumor growth, and exert direct cytotoxic effects. In summary, the development of this novel composite nanomaterial, which induces ferroptosis through mitochondrial Ca2+ overload, provides a valuable reference for synergistic and highly effective tumor therapy.

Electrochemical methanol oxidation reaction (MOR) provides a promising route to reduce the anodic overpotential of water electrolysis while co-generating value-added chemicals. However, developing cost-effective catalysts that achieve highly efficient and selective methanol-to-formate conversion remains a significant challenge. In this work, we developed a series of potential cost-effective electrocatalysts synthesized via a hydrothermal–calcination route. Among them, the iron-substituted nickel oxide (Fe-NiO) electrode delivers the highest current density of ∼150 mA cm−2 at 1.60 V vs. RHE, and remarkable MOR selectivity with a formate Faradaic efficiency of ∼100%, largely above control samplesof pristine NiO-, and Fe2O3-based electrode. At a lower external potential of 1.55 V, this electrode presents a remarkable stability, sustaining a high current density over 100 mA cm−2 even at the end of 100 h operation.Advanced characterization combined with density functional theory (DFT) calculations reveals that Fe incorporation modulates the electronic structure of NiO, optimizes the adsorption of key reaction intermediates, and significantly reduces the energy barrier of the rate-determining step. This work establish an effective electronic-structure engineering strategy for designing earth-abundant, high-performance MOR electrocatalysts and provides mechanistic insights into tuning metal oxides for energy-efficient hydrogen co-production.
电化学甲醇氧化反应（MOR）为降低电解水的阳极过电位同时共产高附加值化学品提供了一条很有前途的途径。然而，开发具有成本效益的催化剂，实现高效和选择性的甲醇转化为甲酸盐仍然是一个重大挑战。在这项工作中，我们开发了一系列具有潜在成本效益的电催化剂，通过水热煅烧路线合成。其中，铁取代的氧化镍（Fe-NiO）电极在1.60 V相对于RHE的电流密度最高，为~ 150 mA cm-2，并且具有显着的MOR选择性，甲酸法拉第效率为~ 100%，大大高于原始NiO-和fe2o3电极的对照样品。在较低的外部电位1.55 V下，该电极表现出显著的稳定性，即使在100小时的工作结束时，也能保持超过100 mA cm-2的高电流密度。高级表征结合密度泛函理论（DFT）计算表明，Fe掺入调节了NiO的电子结构，优化了关键反应中间体的吸附，并显著降低了速率决定步骤的能垒。这项工作为设计地球资源丰富的高性能MOR电催化剂建立了有效的电子结构工程策略，并为调整金属氧化物以实现节能制氢提供了机制见解。

Unraveling the reaction mechanism of the electrochemical CO2 reduction reaction (CO2RR) is a cornerstone in the quest for high-performance catalysts. This work adopts S-doped NiN4 (NiN3S1) as a probe to reveal the synergistic promotion of local coordination and the reaction microenvironment on CO2RR. The results show that N, S-coordination decreases the required potential for CO2 chemical adsorption from −0.54 to −0.23 V. An explicit water-assisted mechanism for CO2 activation is demonstrated, where H2O molecules act as proton donors and form hydrogen-bond networks to facilitate CO2 activation and reduce the reaction energy for *COOH formation. The applied potential (U) vs. Standard Hydrogen Electrode (SHE) promotes electron transfer and proton-coupled processes, thus improving the intermediate adsorption and reaction activity. As a result, the limiting potential of CO2RR to CO decreases from −1.38 to −0.48 V with the increase in applied potential (U) vs. SHE from 0 to −0.84 V. Hydrogen evolution reaction on NiN3S1 is investigated as well to reflect the high CO2RR selectivity. The results of this work highlight the synergistic promotion of coordination environment, explicit water molecules, and applied potential (U) vs. SHE to efficient CO2RR, providing theoretical guidance for designing advanced CO2RR electrocatalysts.

Low-temperature CO2 methanation efficiently enables efficient conversion of CO2 into methane under mild conditions, presenting substantial potential for enhanced energy efficiency and economic feasibility. However, achieving highly efficient low-temperature CO2 activation remains a critical challenge due to inherent kinetic constraints. In this study, the inverse-supported Ce/Ni catalyst (11 mol% Ce/Ni) was synthesized, which achieved 82% CO2 conversion and nearly 100% CH4 selectivity under photothermal synergy at 220 °C (300 W xenon lamp, 300–2500 nm, 1.5 W·cm−2), outperforming most conventional nickel-based catalysts. Moreover, the catalyst exhibited outstanding long-term stability, with only an 8% activity loss after 100 h of continuous operation. This superior performance was attributed to its CeO2-Ni interfacial configurations and abundant oxygen vacancies. In situ diffuse reflectance infrared Fourier transform spectroscopy analysis revealed that the CO₂ methanation over this catalyst proceeds via a dual-intermediate pathway involving CO* and HCOO*, with photothermal synergy significantly accelerating the intermediate conversion without altering the intrinsic reaction pathway. This study establishes an innovative strategy for designing low-temperature and high-performance CO2 methanation catalysts via the integration of an inverse Ce/Ni configuration with photothermal synergy.

Heterojunction construction has been widely regarded as a pivotal strategy for enhancing photocatalytic CO2 conversion of Ni-MOF and employing the post-synthetic modification (PSM) strategy can further improve the electron transport efficiency and increase the reaction active sites of MOF-based materials. Hence, in this study, a novel SiC/Ni-MOF derivatives dual heterojunction (Ni/C/SiC/Ni-MOF) with Schottky and Type-II was designed and synthesized via an in-situ hydrothermal followed by pyrolysis in N2 atmosphere. The metallic Ni nanoparticles formed during pyrolysis acted simultaneously as active sites and electron accumulation hubs. Furthermore, the strong interfacial interactions of SiC/Ni-MOF type-II heterojunction and Schottky barrier between Ni and SiC facilitated efficient charge transfer across the interfaces. The coexistence of defective C and graphitic C optimized the adsorption of CO₂ and electron transport. In-situ DRFTIR analysis confirmed the formation of key intermediates *COOH and *CHO, which are vital for CO2 conversion to CO and CH4. Density functional theory (DFT) calculations revealed the electron transfer route with the existence of internal electron field (IEF). Meanwhile, the energy level matching among graphitic C, SiC and Ni resulted in the accumulation of electrons on metallic Ni. Under simulated sunlight irradiation, the evolution rates of CO and CH4 on SiC/Ni-MOF pyrolyzed at 400 °C (S/N-400) achieved 7.42 μmol·g−1·h−1 and 16.75 μmol·g−1·h−1, respectively with a CH4 selectivity as high as 90.0%. This work provides a feasible strategy for constructing dual heterojunction with synergistic effects to accomplish efficient CO2 conversion.

In this study, an anion exchange, electrolytic reactor and membrane contactor coupled system (AE-ER-MC) was developed for high-performance recovering (NH4)2SO4 from the low-concentration NO3− contaminated groundwater, where the basic anion exchange resin selectively removed NO3− from the groundwater, the NO3− exhausted resin was regenerated by the NaCl catholyte, and ammonia was produced from the NO3− reduction at the Fe2O3-Ov cathode and recovered by membrane stripping process. The AE-ER-MC system achieved at 98% NO3− removal efficiency and 81% ammonia recovery efficiency at a current density of 20 mA cm−2 with the energy consumption of 19.78 kWh kg−1(NH4)2SO4, which was only 1 % of that of the ER-MC system. The AE-ER-MC system showed stable treatment performance in consecutive cycles with the ammonia recovery efficiency at near 80%. The direct electron transfer reaction was mainly responsible for the NO3− reduction at Fe2O3-Ov at cathode. The DFT calculation results shows that NO3− more favorably adsorbed at Fe2O3-Ov and could undergo spontaneous bond breaking of NO bond with the formation of NO2−, bypassing the conversion of ⁎NO3− to *NO3H step in typical NO3− reduction process. In present combined system, the hardness ions were hardly present in the catholyte since the repulsion effect of basic anion exchange resin. And the developed system did not suffer from the cathode passivation, potential risk of membrane fouling, secondary pollution from high-salt regenerant. Generally, the AE-ER-MC system offers a meaningful paradigm for the design of energy-efficient and resource-recovery technique toward low-concentration NO3− water treatment.
本研究采用阴离子交换-电解反应器-膜接触器耦合系统（AE-ER-MC）从低浓度NO3 -污染的地下水中高效回收（NH4）2SO4，其中碱性阴离子交换树脂选择性去除地下水中的NO3 -， NO3 -排放的树脂被NaCl阴极液再生，Fe2O3-Ov阴极上的NO3 -还原产生氨，并通过膜剥离工艺回收。在电流密度为20 mA cm−2时，AE-ER-MC系统的NO3−去除率为98%，氨回收率为81%，能耗为19.78 kWh kg−1(NH4)2SO4，仅为ER-MC系统的1%。AE-ER-MC系统在连续循环中表现出稳定的处理性能，氨回收率接近80%。在Fe2O3-Ov阴极上，直接电子转移反应是NO3−还原的主要原因。DFT计算结果表明，NO3−在Fe2O3-Ov上的吸附更有利，NO2−的形成使NO键自发断键，绕过了典型NO3−还原过程中由NO3−转化为*NO3H的步骤。在本组合体系中，由于碱性阴离子交换树脂的排斥作用，硬离子在阴极液中几乎不存在。该系统不存在阴极钝化、膜污染、高盐再生剂二次污染等问题。总的来说，AE-ER-MC系统为低浓度NO3−水处理的节能和资源回收技术设计提供了有意义的范例。

Functionalized cobalt phthalocyanine (CoPc) supported on carbon supports are promising electrocatalyst for the electrochemical reduction of carbon dioxide (eCO2RR), yet the role of functional groups on catalytic activity is pending for clarification and optimization to maximize the reaction kinetics. Herein, a series of eCO2RR catalysts are fabricated by affixing functionalized molecular catalysts onto the nitrogen-doped porous carbon (NPC), denoted as CoPc-4x@NPC (x = H, NH2 and NO2). Among them, CoTNPc@NPC exhibits exceptional eCO2RR performance: in an H-type cell, it achieves a current density of 45 mA cm−2 at −0.91 V vs. RHE with CO Faradaic efficiency (FECO) exceeding 93.5% over a wide potential range, long-term stability over 40 h, and a remarkable turnover frequency (TOF) of 23.49 s−1. In a flow cell configuration, the CO partial current density (JCO) further increases to 224.1 mA cm−2 at −0.91 V. Density functional theory (DFT) calculations reveal that the nitro group upshifts the d-band center, enhances Co center electrophilicity, pre-donates electrons for *COOH formation, and underlies the higher turnover frequency. Integrating CoTNPc@NPC into a Zn-CO2 battery delivers a maximum discharge power density of 3.86 mW cm−2 and stable operation for over 15 h. This work highlights the potential of molecularly engineered CoPc catalysts for eCO2RR and Zn-CO2 battery applications, providing new insights for the rational design of high-performance electrocatalysts.
碳载体负载的功能化酞菁钴（CoPc）是一种很有前途的电化学还原二氧化碳（eCO2RR）电催化剂，但官能团对催化活性的作用有待于澄清和优化，以最大限度地提高反应动力学。本文通过将功能化分子催化剂附着在氮掺杂的多孔碳（NPC）上，表征为CoPc-4x@NPC (x = H， NH2和NO2)，制备了一系列eCO2RR催化剂。其中CoTNPc@NPC表现出优异的eCO2RR性能：在h型电池中，与RHE相比，在- 0.91 V下，其电流密度为45 mA cm−2，CO法拉第效率（FECO）在宽电位范围内超过93.5%，40 h以上的长期稳定性，以及23.49 s−1的显著周转频率（TOF）。在流动电池结构中，CO的分电流密度（JCO）在−0.91 V时进一步增加到224.1 mA cm−2。密度泛函理论（DFT）计算表明，硝基提升了d带中心，增强了Co中心的亲电性，为*COOH的形成预先提供了电子，并奠定了更高的转换频率。将CoTNPc@NPC集成到Zn-CO2电池中，最大放电功率密度为3.86 mW cm - 2，稳定运行超过15小时。这项工作突出了分子工程CoPc催化剂在eCO2RR和Zn-CO2电池中的应用潜力，为高性能电催化剂的合理设计提供了新的见解。

The inherent kinetic challenges posed by the robust OO and OH bonds in peroxymonosulfate (PMS) significantly hinder contaminant degradation in advanced oxidation processes (AOPs). In this study, we develop a boron‑nitrogen coordinated cobalt single-atom catalyst (SA-Co-BN) through defect-assisted atomic confinement to overcome these limitations. Both experimental and theoretical investigations demonstrate that the low electronegativity of boron induces charge redistribution at the cobalt sites, thereby synergistically enhancing charge transfer dynamics and lowering proton transfer barriers. This facilitates the selective generation of high-valent cobalt-oxo species (Co(IV)O) and singlet oxygen (1O2) as predominant non-radical oxidants, effectively circumventing scavenging effects by background anions. The SA-Co-BN + PMS system achieves 91.2% removal of tetracycline (TC) within 30 min (kinetic constant: 0.071 min−1), representing more than a twofold increase compared to conventional CoN4 single-atom catalysts (SACs). Furthermore, it maintains over 80% efficiency across a broad pH range (3–11) and in complex matrices, such as wastewater containing 5 mM Cl−/CO32−. Quantitative structure-activity relationship analyses reveal strong correlations between contaminant degradation kinetics and molecular descriptors, including hydrophilicity, energy gap (ΔE), and electrophilicity index. Importantly, a continuous-flow reactor employing immobilized SA-Co-BN exhibits operational stability for 680 min with 80% contaminant removal, while toxicity assessments confirm a significant reduction in the ecotoxicity of degradation intermediates. This work establishes an atomic-scale design principle for heteroatom-modulated SACs, thereby advancing non-radical oxidation technologies toward practical applications in water purification.
过氧单硫酸盐（PMS）中OO键和OH键所带来的固有动力学挑战严重阻碍了高级氧化过程（AOPs）中污染物的降解。在这项研究中，我们通过缺陷辅助原子约束开发了硼氮配位钴单原子催化剂（SA-Co-BN）来克服这些限制。实验和理论研究都表明，硼的低电负性诱导钴位点的电荷重新分布，从而协同增强电荷转移动力学并降低质子转移势垒。这促进了高价钴氧（Co(IV)O）和单线态氧（1O2）作为主要的非自由基氧化剂的选择性生成，有效地规避了背景阴离子的清除作用。SA-Co-BN + PMS体系在30分钟内达到91.2%的四环素（TC）去除率（动力学常数：0.071 min−1），比传统的CoN4单原子催化剂（SACs）提高了两倍以上。此外，它在广泛的pH范围（3-11）和复杂基质（如含有5 mM Cl - /CO32 -的废水）中保持80%以上的效率。定量的结构-活性关系分析揭示了污染物降解动力学与分子描述符之间的强相关性，包括亲水性，能隙（ΔE）和亲电性指数。重要的是，采用固定化SA-Co-BN的连续流反应器在680分钟内表现出运行稳定性，污染物去除率为80%，而毒性评估证实降解中间体的生态毒性显著降低。这项工作建立了杂原子调制SACs的原子尺度设计原则，从而推动了非自由基氧化技术在水净化中的实际应用。

Surface ligands are crucial for perovskite quantum dot (PQD) optoelectronics. However, long alkyl chains limit charge transport, while short chains destabilize their soft lattice, presenting a stability–mobility dilemma. Moreover, surface-bound protonated primary amines are susceptible to deprotonation, accelerating performance decay and structural collapse. In this work, we introduced tetrabutylphosphonium bromide (TBPB) as a surface passivation ligand to overcome these limitations. TBPB combines minimal molecular polarity—enabling a short chain for superior charge transport—with a fully coordinated phosphonium center that resists deprotonation and passivates halogen vacancies. This yields quantum dots with near-unity PLQY and robust stability, leading to LEDs achieving a maximum external quantum efficiency (EQE) of 24.28% and luminance of 122,786 cd m−2, far surpassing control devices. Further shortening the ligand chain increases EQE to 27.89% but at the cost of severe luminance loss, underscoring the delicate balance in ligand engineering.
表面配体是钙钛矿量子点（PQD）光电子学研究的关键。然而，长烷基链限制了电荷输运，而短链使其软晶格不稳定，出现了稳定-迁移的困境。此外，表面结合的质子化伯胺容易发生去质子化，加速性能衰减和结构崩溃。在这项工作中，我们引入了四丁基溴化磷（TBPB）作为表面钝化配体来克服这些局限性。TBPB结合了最小的分子极性-使短链具有优越的电荷传输-与完全协调的磷中心，抵抗去质子化和钝化卤素空位。这产生了具有接近统一PLQY和鲁棒稳定性的量子点，导致led实现24.28%的最大外部量子效率（EQE）和122,786 cd m-2的亮度，远远超过控制设备。进一步缩短配体链将EQE提高到27.89%，但代价是严重的亮度损失，强调配体工程中的微妙平衡。
