Plasmonic nanomaterials are sources of light,heat and electrons at nanometer scale.Given the outstand-ing performance in harvesting and converting solar energy under visible light irradiation,hybrid nano-materials with plasmonic activity have recently emerged as a new class of advanced photocatalysts.Because of the enhanced charge-separation at hybrid interfaces,the hybrids usually exhibit higher cat-alytic activity compared with their monometallic counterparts.Here,we review the recent progress on synthesis of plasmonic hybrid nanomaterials and their applications in photocatalysis,including H2 pro-duction,CO2 reduction and N2 fixation.We hope this review will give systematic and valuable reference on plasmonic solar to chemical energy conversion.
