摘要:

面对日益严峻的全球能源危机与环境污染问题, 开发清洁、可再生的替代能源已成为人类社会可持续发展的迫切需求. 氢能因其极高的能量密度且燃烧产物仅为水, 被视为最具潜力的理想绿色能源之一. 在众多制氢技术中, 利用太阳能驱动的光催化水分解制氢技术能够直接将取之不尽的太阳能转化为高附加值的化学能, 具有广阔的应用前景. 然而, 传统光催化剂普遍面临光生载流子复合严重、表面催化反应动力学缓慢等瓶颈. 近年来, 单原子催化剂(SACs)因其100%的原子利用率、独特的量子尺寸效应以及高度可调的配位环境, 在光催化领域引起了极大关注. 本综述系统梳理了贵金属与非贵金属单原子光催化剂的最新研究进展, 旨在为高效太阳能-氢能转换系统的设计提供深刻的理论指导与重要参考.

本文以单原子催化剂在光催化制氢中的核心机制为切入点, 全面探讨了其设计理念、性能提升及内在构效关系. 首先, 重点概述了单原子催化剂的基本原理, 并详细阐述了实现金属原子在载体上原子级分散以及提高活性位点密度的合理设计策略(如缺陷工程、空间限域效应及配位锚定等). 随后, 系统性地总结并对比了贵金属(如Pt, Pd, Ag, Au, Ru和Rh)与非贵金属(如Co, Cu, Ni, Fe和Mo)单原子光催化剂在增强制氢活性方面的具体表现. 贵金属单原子凭借其优异的本征活性展现出极高的产氢速率, 而非贵金属单原子则因其地球储量丰富、成本低廉, 在经过配位环境优化后展现出媲美甚至超越贵金属的巨大潜力. 在反应机理层面, 本文深入探究了单原子引入对光催化体系电荷转移行为的根本影响. 特别聚焦于电荷分离、定向电荷转移以及空间限定的电子离域效应. 通过对光生载流子动力学的详细解析, 揭示了中心金属原子与其周围配位原子的配位环境依赖性, 明确了配位构型与宏观催化性能之间的构效关系, 为定向调控光催化产氢性能提供了详实的理论支撑.

最后, 本文客观讨论了当前高效单原子催化剂在规模化制备、工况条件下的结构稳定性以及动态活性位点精准表征等方面所面临的挑战. 本文通过总结基本原理与机制见解, 为推动光催化单原子制氢技术从实验室基础研究迈向实际太阳能转换的工业化应用提供了极具价值的科学指导.

Abstract:

This review presents a comprehensive overview of noble (Pt, Pd, Ag, Au, Ru, and Rh) and earth abundant metals (Co, Cu, Ni, Fe, and Mo) single-atom-based photocatalysts (SACs) for hydrogen (H2) production. We first highlight the fundamental of SACs followed by rational design strategies to achieve atomic-level distribution, and increase the density of active sites. Then, thoroughly summarize the enhanced H2 production activity of noble and earth abundant metal-based SACs. Moreover, insights into the charge transfer mechanisms, such as charge separation, transfer, and spatially defined electron delocalization to unravel the structure-activity relationship and coordination-dependent catalytic performance. Finally, we discuss recent challenges and prospects for designing highly effective SACs. Overall, this review provides a valuable guidance by highlighting fundamental principles of SACs, performance assessment, and mechanistic insights toward practical solar-to-H2 conversion.
