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 si...
