Abstract

Photocatalytic water splitting into H₂ is considered an economical and environmentally friendly method for H₂ evolution, and rationally designing a non-noble metal cocatalyst maintains an enormous effect on a photocatalytic system. Herein, with metallic FeP, introducing n-type semiconductor CdIn₂S₄ induces a rapid charge transfer across the FeP/CdIn₂S₄ Schottky junction, furthering improved photocatalytic activity. The optimal FeP/CdIn₂S₄ composite presents an impressive hydrogen evolution rate of 1.28 mmol·g⁻¹·h⁻¹, which was nearly 9.8 times higher than that of CdIn₂S₄ (0.13 mmol·g⁻¹·h⁻¹). Quantum efficiency can reach up to 14.5 % at 420 nm. Systematic investigations reveal that FeP can be reserved as a cocatalyst, providing more reactive sites and lower overpotential for hydrogen evolution. This work offers a new strategy for designing and fabricating efficient photocatalytic energy conversion cocatalysts.

将磷化铁整合到 CdIn2S4 上可加速载流子分离，实现高效光催化氢气进化

光催化水裂解成H2被认为是一种经济、环保的析氢方法，合理设计非贵金属助催化剂对光催化系统有着巨大的影响。通过金属FeP，引入n型半导体CdIn2S4诱导FeP/CdIn2S4肖特基结的快速电荷转移，进一步提高了光催化活性。最佳FeP/CdIn2S4复合材料的析氢速率为1.28 mmol·g−1·h−1，是CdIn2S4 （0.13 mmol·g−1·h−1）的近9.8倍。在420纳米处，量子效率可达14.5%。系统研究表明，FeP可以作为助催化剂保留，为析氢提供更多的反应位点和更低的过电位。这项工作为设计和制造高效的光催化能量转换助催化剂提供了新的思路。
