Enhanced photocatalytic activities by Au core Novel Au/Cu2 ZnSnS4 core/shell nanoparticles (NPs) are synthesized for the first time via wet chemistry approach. The insertion of Au core into CZTS NPs dramatically enhances light absorption due to surface plasmon resonance effect, especially in the Vis-NIR region. Au/CZTS core/shell NPs show much higher photocatalytic activities for hydrogen evolution compared with other CZTS nanostructures.
通过湿化学法首次合成了具有 Au 核的新型 Au/Cu2 ZnSnS4 核/壳纳米粒子（NPs），以提高光催化活性。由于表面等离子体共振效应，Au 核的插入使 CZTS NPs 的光吸收显著增强，尤其是在可见-近红外区域。与其他 CZTS 纳米结构相比，Au/CZTS 核/壳 NPs 具有更高的光催化析氢活性。
