Plasmon-enhanced electrocatalysis from synergistic hybrids of noble metal nanocrystals

Summary Noble metal nanocrystals (NCs) with controlled morphologies and compositions have shown great applicable potentials as electrocatalytic materials. Recently, the incorporation of plasmonic function into NC-based electrocatalysts has been considered as a highly promising approach to promote the electrocatalytic activity and stability due to the synergism between plasmonic and catalytic functions. This review highlights the latest advancements in plasmon-enhanced electrocatalysis with multi-metallic heteronanostructures with integrated plasmonic and catalytic functions. We also provide a perspective for designing new types of heteronanostructures for plasmon-enhanced electrocatalysis, which can be useful to the development of a new class of energy conversion systems.
