With the past decade of worldwide sustained efforts on artificial photosynthesis for photocatalytic solar water splitting and clean hydrogen generation by dedicated researchers and engineers from different disciplines, substantial progress has been achieved in raising its overall efficiency along with finding new photocatalysts. Various materials, systems, devices, and better fundamental understandings of the interplay between interfacial chemistry, electronic structure, and photogenerated charge dynamics involved have been developed. Nevertheless, the overall photocatalytic performance is yet to achieve its maximum theoretical limit. Moreover, the stability of well-known semiconductors (as well as novel ones) remains the biggest challenge that scientists are facing to develop durable industrial-scale devices for large-scale water oxidation and overall solar water splitting. In this Perspective, we summarize the major achievements and the different approaches carried out to improve the stability and performance of photoelectrodes based on sulfide, nitride, and phosphide semiconductors.
在过去十年里，来自不同学科的专业研究人员和工程师在全球范围内持续致力于人工光合作用以实现光催化太阳能水分解和清洁制氢，在提高其整体效率以及寻找新型光催化剂方面取得了重大进展。已开发出各种材料、系统、装置，并对涉及的界面化学、电子结构和光生电荷动力学之间的相互作用有了更好的基础认识。然而，整体光催化性能尚未达到其最大理论极限。此外，著名半导体（以及新型半导体）的稳定性仍然是科学家们在开发用于大规模水氧化和整体太阳能水分解的耐用工业规模装置时面临的最大挑战。在本观点文章中，我们总结了基于硫化物、氮化物和磷化物半导体的光电极在提高稳定性和性能方面所取得的主要成就及采用的不同方法。
