Abstract

We demonstrate plasmon-enhanced hydrogen evolution from photocatalytic water reduction using Au-InVO₄ hybrid microspheres. The surface plasmons of gold nanoparticles enhance the sub-band gap excitation of InVO₄ and promote charge separation on its surface through plasmon-exciton coupling, thereby significantly improving their photocatalytic efficiency.
