Advancing towards alternative technologies for the sustainable production of hydrogen is a necessity for the successful integration of this potentially green fuel in the future. Photocatalytic and photoelectrochemical water splitting are promising concepts in this context. Over the past decades, researchers have successfully explored several materials classes, such as oxides, nitrides, and oxynitrides, in their quest for suitable photocatalysts with a focus on reaching higher efficiencies. However, to pave the way towards practicability, understanding degradation processes and reaching stability is essential, a domain where research has been scarcer. This perspective aims at providing an overview on recent progress concerning stability and degradation with a focus on (oxy)nitride photocatalysts and at providing insights into the opportunities and challenges coming along with the investigation of degradation processes and the attempts to improve the stability of photocatalysts.
为了在未来成功整合这种潜在的绿色燃料，开发可持续制氢的替代技术势在必行。在这种背景下，光催化和光电化学水分解是很有前景的概念。在过去几十年里，研究人员在寻找合适的光催化剂以提高效率的过程中，成功探索了几种材料类别，如氧化物、氮化物和氧氮化物。然而，为了迈向实用性，了解降解过程并实现稳定性至关重要，而这一领域的研究相对较少。本观点旨在概述有关稳定性和降解的最新进展，重点关注（氧）氮化物光催化剂，并深入探讨降解过程研究以及提高光催化剂稳定性尝试所带来的机遇和挑战。
