The notorious shuttle effect of polyiodides in aqueous Zinc-iodine (Zn-I2) batteries impedes their practical application, which renders it imperative to address this issue. Here, we report natural gelatin as an advanced aqueous binder for iodine-loading cathode to enable stable and efficient Zn-I2 batteries. The positively charged region in gelatin presents electrostatic attraction to the iodine species, while the electron-rich regions could donate electrons to form physical or even covalent bonds with iodine species, thus inhibiting polyiodides shuttle effect and boosting redox reaction. A high reversible capacity of 138 mAh g−1 after 3 000 cycles at 2C and an ultra-long cycling stability of 30 000 cycles at 25C with 107 mAh g−1 capacity was achieved. Gelatin binder also can accommodate high iodine-loading (∼10 mg) cathode, punch cells, and severe temperature conditions (−10 °C and 60 °C). In-situ UV–vis absorption spectroscopy, in-situ Raman spectra and theoretical calculation revealed the critical role of gelatin binder in suppressing polyiodide shuttling and accelerating reaction kinetics. This work uncovers the potential of natural low-cost binder material in advanced Zn-I2 batteries and drives future study of designing functional binders.
多碘化物在水相锌-碘（Zn-I2）电池中臭名昭著的穿梭效应阻碍了它们的实际应用，这使得解决这一问题势在必行。在这里，我们报道了天然明胶作为一种先进的水粘合剂的碘负载阴极，使稳定和高效的锌- i2电池。明胶中带正电的区域对碘种具有静电吸引作用，而富电子的区域可以给电子与碘种形成物理甚至共价键，从而抑制多碘化物的穿梭效应，促进氧化还原反应。在2C条件下，经过3000次循环，获得了138 mAh g−1的高可逆容量，在25℃条件下，获得了107 mAh g−1容量，30万次的超长循环稳定性。明胶粘合剂还可以适应高碘负载（~ 10毫克）阴极，冲孔电池和恶劣的温度条件（−10°C和60°C）。原位紫外-可见吸收光谱、原位拉曼光谱和理论计算揭示了明胶粘结剂在抑制多碘化物穿梭和加速反应动力学方面的关键作用。这项工作揭示了天然低成本粘结剂材料在先进锌- i2电池中的潜力，并推动了未来功能粘结剂设计的研究。

Zinc-iodine (Zn-I2) batteries are deemed as potential candidate of energy storage system for the merits of high safety, cost-effectiveness, high capacity, and environmental compatibility. Unfortunately, the practical implementation of Zn-I2 batteries is still hindered by the sluggish iodine redox kinetics and the shuttle effect of soluble polyiodides, which induce rapid capacity decay and electrode interface passivation. This work proposes platinum/carbon (Pt/C) and iridium/carbon (Ir/C) composite as conductive catalytic iodine hosts, which realizes the physical confinement for active iodine through the intrinsic porous structure. The introduction of active Pt/Ir sites effectively anchors the polyiodides through chemical adsorption capability, and inhibits shuttle effect and Zn metal corrosion. In addition, the superior electrical conductivity and catalytic activity of Pt/C and Ir/C carriers also contribute to reduce the reaction energy barriers, significantly promoting the electrochemical performance and conversion reaction kinetics. As expected, the assembled Zn//Pt/C@I2 and Zn//Ir/C@I2 batteries achieve impressive reversible capacity of 132.2 and 108 mAh g−1 after 2 000 cycles at 200 mA g−1, respectively, and their capacity retention rate after 25 000 cycles at 1 000 mA g−1 are as high as 88.1 % and 85.9 %. This study will guide the carrier design of iodine cathode to drive the application of high-performance Zn-I2 batteries.
锌-碘（Zn-I2）电池具有高安全性、高性价比、高容量和环境兼容性等优点，被认为是储能系统的潜在候选材料。不幸的是，锌- i2电池的实际应用仍然受到碘氧化还原动力学缓慢和可溶性多碘化物的穿梭效应的阻碍，这导致了快速的容量衰减和电极界面钝化。本文提出铂/碳（Pt/C）和铱/碳（Ir/C）复合材料作为导电催化碘载体，通过其固有的多孔结构实现对活性碘的物理约束。活性Pt/Ir位的引入通过化学吸附能力有效地锚定了多碘化物，抑制了穿梭效应和锌金属的腐蚀。此外，Pt/C和Ir/C载体优越的导电性和催化活性也有助于降低反应能垒，显著提高电化学性能和转化反应动力学。正如预期的那样，组装的Zn//Pt/C@I2和Zn//Ir/C@I2电池在200 mA g - 1下循环2 000次后分别获得了132.2和108 mAh g - 1的可逆容量，并且在1 000 mA g - 1下循环25 000次后的容量保持率高达88.1%和85.9%。本研究将指导碘阴极的载流子设计，带动高性能锌离子电池的应用。

The adsorption/desorption of OH∗ on electrode surfaces is pivotal in numerous electrocatalytic reactions. To understand the effect of electrolyte pH on that process, in this work, an advanced approach combining ab initio molecular dynamics (AIMD) with free energy perturbation is employed to calculate the dehydrogenation free energy of water chemisorbed at differently electrified Pt(111)/electrolyte interfaces. Our findings reveal that the onset potential for OH∗ formation shifts negatively as the pH increases at low pH condition (pH4.3), aligning with the cyclic voltammetry curves observed in experimental studies. It indicates the dissociation of chemisorbed water is the primary route for OH∗ adsorption at low pH condition. Furthermore, it is also found that the variation in dehydrogenation energy across different pH is primarily due to the local hydrogen bonding network surrounding the chemisorbed water. In addition, it is proposed that at high pH conditions OH− oxidation emerges as the primary route for OH∗ adsorption on Pt(111) constrained by the water chemisorption process. This work provides crucial insights into the pH-dependent adsorption behavior of OH∗ on the Pt(111) surface and aims to guide the optimization of electrolytes to boost the efficiency of related reactions.

The evolution of energy storage technology has seen remarkable progress, with a shift from pure metals to sophisticated, tailor-made active materials. The synthesis of nanostructures with exceptional properties is crucial in the advancement of electrode materials. In this regard, our study highlights the fabrication of a novel, oriented heterostructure comprised of Zn-Mn-Co-telluride grown on a pre-oxidized copper mesh using a hydrothermal method followed by a solvothermal process. This innovative approach leads to the formation of the Zn-Mn-Co-telluride@CuO@Cu heterostructure, which demonstrates the unique oriented morphology. It outperforms both Zn-Mn-Co-telluride@Cu and CuO@Cu by exhibiting lower electrical resistivity, increased redox activity, higher specific capacity, and improved ion diffusion characteristics. The conductivity enhancements of the heterostructure are corroborated by density functional theory (DFT) calculations. When utilized in a hybrid supercapacitor (HSC) alongside activated carbon (AC) electrodes, the Zn-Mn-Co-telluride@CuO@Cu heterostructure-based HSC achieves an energy density of 75.7 Wh kg−1. Such findings underscore the potential of these novel electrode materials to significantly impact the design of next-generation supercapacitor devices.

The electrochemical reduction reaction of carbon dioxide (CO2-ERR) holds tremendous potential as a key approach for achieving carbon neutrality by harnessing renewable resources.
However, the current state of CO2-ERR encounters challenges in terms of efficiency and selectivity. Overcoming these obstacles requires the development of a robust electrocatalyst capable of enhancing process efficiency and improving selectivity towards desired products. In recent years, 2D materials have garnered significant attention as efficient catalysts. Among them, MXene stands out of high interest due to unique multilayered structure and presence of surface functional moieties. The MXene material offers high electrical conductivity, versatile surface chemistry, and tunable interface designs. This comprehensive review explores the utilization of MXene-based catalysts for CO2-ERR into valuable products. It covers fundamental aspects of electrochemical conversion, including CO2 adsorption on MXene Ti3C2Tx, the mechanism of CO2-ERR on MXene (Mo2CS2) single-atom catalysts, applications, synthesis methods of MXene production, and future prospects. Additionally, the review highlights the significance of modern artificial intelligence techniques, particularly machine learning, in screening and activating CO2, making it a pioneering scientific endeavor.

Pulsed-laser deposition has been developed to prepare large-area In2S3 nanofilms and their photoelectric characteristics have been investigated. The In2S3 nanofilm grown under 500 °C is highly oriented along the (103) direction with exceptional crystallinity. The corresponding (103)-oriented In2S3 photodetectors exhibit broadband photoresponse from 370.6 nm to 1 064 nm. Under 635 nm illumination, the optimized responsivity, external quantum efficiency, and detectivity reach 19.8 A/W, 3 869%, and 2.59 × 1012 Jones, respectively. In addition, the device exhibits short rise/decay time of 3.9/3.0 ms. Of note, first-principles calculations have unveiled that the effective carrier mass along the (103) lattice plane is much smaller than those along the (100), (110) and (111) lattice planes, which thereby enables high-efficiency transport of photocarriers and thereby the excellent photosensitivity. Profited from the sizable bandgap, the In2S3 photodetectors also showcase strong robustness against elevated operating temperature. In the end, proof-of-concept imaging application beyond human vision and under high operating temperature as well as heart rate monitoring have been achieved by using the In2S3 device of the sensing component. This study introduces a novel crystal orientation engineering paradigm for the implementation of next-generation advanced optoelectronic systems.

Osteochondral defects pose an enormous challenge, and no satisfactory therapy is available to date due to the hierarchy of the native tissue consisting of articular cartilage and subchondral bone. Constructing a scaffold with biological function and biomimetic structure is the key to achieving a high-quality repair effect. Herein, a natural polymer-based bilayer scaffold with a porous architecture similar to that of osteochondral tissue is designed, involving the transforming growth factor-beta3-liposome-loaded upper layer for superficial cartilage regeneration and the nanohydroxyapatite-coated lower layer for subchondral bone rehabilitation. This research is conducted to evaluate the effects of nanoparticle-modified bilayer scaffold to mimic the hierarchical pro-chondrogenic and pro-osteogenic microenvironment for the recruited endogenous bone marrow mesenchymal stem cells. The fabricated composites were evaluated for mechanical, physicochemical, biological properties, in vitro and in vivo tissue regeneration potential. Overall, the current bilayer scaffold could regenerate a cartilage-bone integrated tissue with a seamless interfacial integration and exhibited superior tissue repair outcomes compared to other single layer scaffolds based on morphological, radiological and histological evaluation, verifying that this novel graft could be an effective approach to tissue-engineered analogs of cartilage-subchondral bone and offer new therapeutic opportunities for osteochondral defect-associated diseases.

With the rapid advancement of science and technology, along with an increasing global focus on space exploration, there is a growing concern for addressing friction and wear issues in surface coatings for components operating in high-temperature environments within the aerospace sector. However, typical high-temperature coatings currently face challenges in effectively integrating excellent oxidation resistance, wear resistance, and lubrication properties in high-temperature settings. Studies have demonstrated the significant potential of Transition Metal Dichalcogenides (TMDCs) as lubricant additives in high-temperature lubrication, attributable to their distinctive crystal structures. Thus, this review concentrates on the compositional design of individual MX2-type (M = W, Mo, Nb, Ta; X = S, Se) TMDCs (molybdenum disulfide (MoS2), tungsten disulfide (WS2), niobium diselenide (NbSe2), molybdenum diselenide (MoSe2), tungsten diselenide (WSe2)) and their composites, including inorganic oxygen-containing sulfides, and explores the utilization of TMDCs in self-lubricating coatings. Furthermore, conventional preparation methods (mechanical exfoliation, liquid-phase ultrasonic exfoliation, chemical vapour deposition) for synthesizing TMDCs are outlined. Finally, an analysis of the lubrication mechanism of MX2-type TMDCs is provided, along with future directions for enhancing the high-temperature lubrication performance of composite coatings.
