The development of efficient and cost-effective non-precious-metal single-atom catalysts (SACs) is crucial for advancing the practical application of electrocatalytic CO2 reduction (CO2RR). However, identifying highly active metal atoms and designing catalysts with uniform active center structures remain significant challenges. To address this, we developed a generic pyrolysis method to synthesize a series of transition metal-based SACs with atomically dispersed metal anchored on carbon nitride support (M-C3N4, M = Fe, Ni, Cu). Benefiting from the unique electronic structure of the Fe-N4 sites supported on C3N4, the Fe-C3N4 catalyst demonstrated exceptional performance, achieving a CO Faradaic efficiency of 99.6 % and maintaining excellent stability. Theoretical calculations indicate that the Fe site exhibits a relatively stronger interaction with the *COOH intermediate, thereby helping to lower the energy barrier of the CO2 protonation process. This study provides valuable theoretical insights and practical synthesis strategies for designing high-performance non-precious-metal SACs for CO2RR.
开发高效、经济的非贵金属单原子催化剂对于推进电催化CO2还原（CO2RR）的实际应用至关重要。然而，鉴定高活性金属原子和设计具有均匀活性中心结构的催化剂仍然是一个重大挑战。为了解决这个问题，我们开发了一种通用的热解方法来合成一系列过渡金属基SACs，这些SACs将原子分散的金属锚定在氮化碳载体上（M- c3n4, M = Fe, Ni, Cu）。得益于C3N4上Fe-N4位独特的电子结构，Fe-C3N4催化剂表现出优异的性能，CO法拉第效率达到99.6 %，并保持了优异的稳定性。理论计算表明，Fe位点与*COOH中间体的相互作用相对较强，从而有助于降低CO2质子化过程的能垒。该研究为设计高性能的CO2RR非贵金属sac提供了有价值的理论见解和实用的合成策略。

In recent years, AgBiS2 nanocrystals (NCs) have emerged as a research hotspot in the field of solar cells due to their excellent optoelectronic properties and environmentally friendly characteristics. Although the theoretical power conversion efficiency (PCE) of AgBiS2 NC solar cells can reach up to 26%, the current best device only achieved a PCE of 10.84%. Such an enormous efficiency gap is primarily caused by the complex surface defects, severe carrier recombination, and undesirable energy-level mismatches. Therefore, this review comprehensively summarizes recent advancements in AgBiS2 NCs, including their crystal structures, optoelectronic properties, synthesis methods, ligand engineering, and device optimization. By fine-tuning synthesis conditions (e.g., temperature, precursor ratios) and employing ligand exchange strategies (solid-state/liquid-state), significant improvements in material performance have been realized. Furthermore, device structure optimization (e.g., transport layer selection, interface modification) and energy-level alignment engineering have further enhanced efficiency. Despite decent stabilities of AgBiS2 NCs, several challenges such as large-area uniformity and long-term device durability remain unraveled, which may be the major obstacles for their further commercialization. Future advancements in defect control, the development of novel ligands, and encapsulation technologies are expected to expand the applications of AgBiS2 NCs in flexible electronics, aerospace, and wearable devices.

Essential oils (EOs) are widely present in aromatic plants and possess a wide range of significant pharmacological activities such as antibacterial, antioxidant and anti-tumor properties. They have broad application prospects in medical care, food, agriculture and other fields. However, their poor stability poses substantial challenges that significantly hinder their development and practical application. Metal-organic framework materials (MOFs), characterized by highly controllable structures, large specific surface areas, and stimuli-responsive release properties, have been extensively utilized in various fields such as drug delivery and food preservation. Due to their capacity to encapsulate and deliver EOs, MOFs have garnered considerable attention. In this review, we systematically summarize the structural features, types, and characteristics of MOFs, as well as the recent advancements in their application for controlled EO release. Furthermore, we focus on discussing engineering strategies aimed at enhancing the encapsulation, release, and delivery of EOs using MOFs. Finally, we briefly outline the existing challenges in the delivery of EOs using MOFs and present well-reasoned insights into prospective directions for future research.

The structural principles of traditional Chinese mortise-and-tenon joints have inspired breakthroughs in supramolecular engineering. Nevertheless, substantial challenges remain in constructing nanoscale supramolecular architectures with precisely controlled giant dimensions. Herein, we report a precision-guided synthetic strategy for constructing giant 2D and 3D supramolecular architectures with rhomboidal motifs, which was achieved through a dovetail joint strategy. Initial assembly of bis-mortise ligand L1 with dovetail tenon ligand L2 in the presence of Cd2+ ions yielded the fundamental bis-rhombic supramolecule R1. Subsequent structural elaboration of the dovetail tenon motif enabled the development of multitopic ligands L3 and L4, which facilitated the construction of expanded architectures of the giant bis-propeller supramolecule R2 and tris-propeller supramolecule R3. The synthesized supramolecules R1–R3 were fully characterized multidimensional NMR spectroscopy, electrospray ionization mass spectrometry (ESI-MS), traveling wave ion mobility mass spectrometry (TWIM-MS), transmission electron microscopy (TEM), and atomic force microscopy (AFM). This work develops an innovative dovetail-joint assembly strategy for constructing rigid giant supramolecular architectures, establishing a new paradigm for precision engineering of complex 3D molecular systems.

Chiral amino acids (AAs) serve as essential building blocks of proteins and play vital physiological roles in living organisms. To achieve accurate, rapid, and high-throughput analysis of chiral AAs, this work proposed a methylbenzyl isocyanate (MBIC) derivatization strategy coupled with ultra-high performance liquid chromatography-mass spectrometry or trapped ion mobility spectrometry-mass spectrometry. The integration of a chiral carbon atom with a rigid urea-based structure can significantly enhance the separation of chiral MBIC-labeled AA enantiomers. This phenomenon can be attributed to the labeled l-AAs allow the carboxyl group to form intramolecular hydrogen bonds with the amino group in the rigid urea-based structure, whereas labeled d-AAs are unable to form such bonds. The method based on MBIC derivatization coupled with ultra-performance liquid chromatography-tandem mass spectrometry achieved simultaneous separation of 19 pairs of chiral AAs using only a C18 column within 30 min, enabling quantitatively detect twelve types of chiral AAs in the serum of healthy humans and Parkinson's patients. The distribution of twenty-four chiral AAs is observed in mouse brain using MBIC labeling-based matrix-assisted laser desorption/ionization-trapped ion mobility spectrometry-mass spectrometry imaging without prior separation. Our work elucidates the principles governing the separation of chiral AAs using derivatization methods, providing valuable guidance for the separation of chiral compounds.

Transforming sunlight into renewable energy sources like hydrogen and methane through photocatalytic water splitting and the CO2 conversion presents a promising prospect to tackle energy scarcity and environmental pollution caused by burning fossil fuels. As the core of the photocatalytic technique, photocatalysts design is most significant for acquiring the desirable catalytic performance and target products. Photonic crystals, also denoted as inverse opals and three-dimensionally ordered macroporous materials (3DOM), have been extensively applied in photocatalytic fields due to their distinct advantages. Specifically, photonic crystal possesses slow photons effect, rich reactive sites, and well-interconnected inner channels. Among the above advantages, the slow photons effect contributes the most essential role for accelerating photocatalytic reaction. However, how to design materials with maximized slow photons effect upon specific wavelength illumination is still in the infancy. Although some reviews about 3DOM photocatalysts have been published, a critical review focusing on tunable slow photons effects for efficient photocatalysis is still lacking. In this review, we highlighted recent advances in slow photons effect in boosting solar energy conversion. Meanwhile, the relevant mechanism and fundamentals of the slow photons effect are discussed. Finally, we present our vision of the future developments and challenges in this exciting research field.

Organic electrochemical transistor (OECT)-based inverters hold great promise for neural-machine interfaces due to their low operating voltage and compatibility with aqueous environments. However, unbalanced p-/n-channel characteristics hinder the inverter’s voltage gain and fast switching. Here, a rational inverter design is presented, leveraging ion concentration to equilibrate p-n channel conductivity and kinetic doping in the OECT inverter, achieving an extremely high gain value of over 370 V/V under optimized driving conditions. Furthermore, a 3-stage ring oscillator constructed from these ion-equilibrated OECT inverters exhibits a rapid response time (stage delay < 0.6 ms) and a broad frequency response exceeding 300 Hz, matching the mechanoreceptor signals in human skin. The biocompatible output displays a sublinear reaction to static pressure pulses, indicating successful tactile recognition in live neurons. This work presents a practical strategy for constructing neural-compatible artificial logics through ion-concentration engineering, providing a platform for seamless neural-machine integration.

The hydrogen evolution reaction (HER) is a pivotal process for clean energy conversion, yet the development of efficient and cost-effective electrocatalysts remains a major challenge. Alloy catalysts, with their tunable electronic properties and promising catalytic performance, have shown great potential for HER. However, the design of component types and ratios, along with structural optimization, has largely relied on traditional trial-and-error approaches, which are very complex and time-consuming. The rise of machine learning (ML) provides an efficient strategy for discovering and optimizing alloy catalysts by enabling rapid analysis of extensive experimental and simulation datasets. This review highlights the recent advances in applying ML techniques for the design and optimization of alloy electrocatalysts for HER, covering binary and multinary (ternary, quaternary and high-entropy alloys). In particular, by employing supervised learning and deep learning techniques, ML has achieved remarkable success in the rapid screening of alloy catalysts and in improving prediction accuracy. It also demonstrates the merit and capability of ML in accelerating this process. In the end, we discuss current challenges and future prospects for integrating ML into advanced HER catalysis, highlighting its potential to revolutionize catalyst development and promote sustainable hydrogen energy solutions.
