Overall water splitting based on particulate photocatalysts is an easily constructed and cost-effective technology for the conversion of abundant solar energy into clean and renewable hydrogen energy on a large scale. This promising technology can be achieved in a one-step excitation system using a single photocatalyst or via a Z-scheme process based on a pair of photocatalysts. Ideally, such photocatalysis will proceed with charge separation and transport unaffected by recombination and trapping, and surface catalytic processes will not involve undesirable reactions. This review summarizes the basics of overall water splitting via both one-step excitation and Z-scheme processes, with a focus on standard methods of determining photocatalytic performance. Various surface engineering strategies applied to photocatalysts, such as cocatalyst loading, surface morphology control, surface modification and surface phase junctions, have been developed to allow efficient one-step excitation overall water splitting. In addition, numerous visible-light-responsive photocatalysts have been successfully utilized as H2-evolution or O2-evolution photocatalysts in Z-scheme overall water splitting. Prototype particulate immobilization systems with photocatalytic performances comparable to or drastically higher than those of particle suspension systems suggest the exciting possibility of the large-scale production of low-cost renewable solar hydrogen.

用于太阳能驱动的总水分解的非均相光催化剂的最新进展
基于颗粒状光催化剂的总水分解是一种易于构建且具有成本效益的技术，可将大量太阳能大量转化为清洁和可再生的氢能。这项有前途的技术可以在使用单一光催化剂的单步激发系统中，或者通过基于一对光催化剂的Z方案工艺来实现。理想地，这样的光催化将进行电荷分离和运输而不受重组和俘获的影响，并且表面催化过程将不涉及不期望的反应。这篇综述总结了通过一步激发和Z方案过程，重点放在确定光催化性能的标准方法上。已经开发了应用于光催化剂的各种表面工程策略，例如助催化剂负载，表面形态控制，表面改性和表面相结，以允许有效的一步激发整体水分解。另外，已经成功地将许多可见光响应性光催化剂用作H 2演化或O 2。Z方案总水分解过程中的-演化光催化剂。具有与颗粒悬浮系统相当或大大高于其光催化性能的原型颗粒固定系统，表明了大规模生产低成本可再生太阳能氢的令人兴奋的可能性。
