Photocatalytic Hydrogen Evolution via Water Splitting: A Short Review

Photocatalytic H-2 generation via water splitting is increasingly gaining attention as a viable alternative for improving the performance of H-2 production for solar energy conversion. Many methods were developed to enhance photocatalyst efficiency, primarily by modifying its morphology, crystallization, and electrical properties. Here, we summarize recent achievements in the synthesis and application of various photocatalysts. The rational design of novel photocatalysts was achieved using various strategies, and the applications of novel materials for H-2 production are displayed herein. Meanwhile, the challenges and prospects for the future development of H-2-producing photocatalysts are also summarized.
