摘要

清洁和可持续能源技术的发展是当代科学研究的一个关键焦点。本研究以氮掺杂的硫空位cdn₂S₄为催化剂，以（nh4） 4 [NiMo 6 O 24 H 6]•5H 2o （NiMo₆）为助催化剂，构建了高效的光催化析氢体系。在所有合成的催化剂中，NiMo₆/10N-CdIn₂S₄（Vs）复合物表现出优异的光催化析氢活性，其产氢率为30.88 mmol•g⁻¹•h⁻¹，是CdIn₂S₄体系中活性最高的。n掺杂和S-空位促进了CdIn₂S₄的光吸收和电荷分离，而多金属氧酸盐（POM）通过促进体系中的电子转移、减少载流子的重组和提高光催化体系的稳定性进一步提高了性能。

Synergistic Effect of Nitrogen-doped CdIn₂S₄(Vs) and Andersontype Polyoxometalate on Enhanced Photocatalytic Hydrogen Production

The development of clean and sustainable energy technologies represents a critical focus in contemporary scientific research. In this study, we construct an efficient photocatalytic hydrogen evolution system using nitrogendoped, sulfur vacancy CdIn₂S₄ as the catalyst and (NH 4 ) 4 [NiMo 6 O 24 H 6 ]•5H 2 O (NiMo₆) as co-catalyst. Among all synthesized catalysts, the NiMo₆/10N-CdIn₂S₄(Vs) composite exhibits superior photocatalytic hydrogen evolution activity, achieving an exceptional production rate of 30.88 mmol•g⁻¹•h⁻¹, which is the highest activity among CdIn₂S₄-based systems. Ndoping and S-vacancies boost the light absorption and charge separation of CdIn₂S₄, while the polyoxometalate (POM) further enhances performance by facilitating electron transfer in the system, minimizing recombination of charge carriers and increasing stability of the photocatalytic system.
