Plasmonic hot electron enhanced MoS2 photocatalysis in hydrogen evolution

Author affiliations

Abstract

With plasmonic hot electron doping, the molybdenum disulfide (MoS2) monolayer with deposited Au@Ag nanorattles effectively enhanced the hydrogen evolution reaction (HER) efficiency. The maximum photocatalysis is achieved under plasmon resonance excitation, and is actively controlled by the incident laser wavelength and power intensity. The localized phase transition of MoS2 is achieved and characterized to explicate this plasmon-enhanced hydrogen evolution. The proposed MoS2-nanoparticle composite combines surface plasmons and planar 2D materials, and pioneers a frontier field of plasmonic MoS2 photocatalysis.
