Synergistic effect of nitrogen-doped CdIn <sub>2</sub> S <sub>4</sub> (Vs) and Anderson-type 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 nitrogen-doped, sulfur vacancy-rich CdIn<sub>2</sub>S<sub>4</sub> as the catalyst and (NH<sub>4</sub>)<sub>4</sub>[NiMo<sub>6</sub>O<sub>24</sub>H<sub>6</sub>]·5H<sub>2</sub>O (NiMo<sub>6</sub>) as the co-catalyst. Among all synthesized catalysts, the NiMo<sub>6</sub>/10N-CdIn<sub>2</sub>S<sub>4</sub>(Vs) composite exhibits superior photocatalytic hydrogen evolution activity, achieving an exceptional production rate of 30.88 mmol g<sup>-1</sup> h<sup>-1</sup>, which is the highest activity among CdIn<sub>2</sub>S<sub>4</sub>-based systems. N-doping and S-vacancies boost the light absorption and charge separation of CdIn<sub>2</sub>S<sub>4</sub>, while the polyoxometalate (POM) further enhances performance by facilitating electron transfer in the system, minimizing recombination of charge carriers and increasing the stability of the photocatalytic system.
