Construction of LSPR-enhanced 0D/2D CdS/MoO3? S-scheme heterojunctions for visible-light-driven photocatalytic H2 evolution

Plasmonic nonmetal semiconductors with localized surface plasmon resonance (LSPR) effects possess extended light-response ranges and can act as highly efficient H2 generation photocatalysts. Herein, an LSPR-enhanced 0D/2D CdS/MoO3?x heterojunction has been synthesized by the growth of 0D CdS nanoparticles on 2D plasmonic MoO3?x elliptical nanosheets via a simple coprecipitation method. Taking advantage LSPR effect nanosheets, light absorption was from 600 nm to near-infrared region (1400 nm). Furthermore, introduction not only provided platform for nanoparticles, but also contributed construction S-scheme structure due interface between CdS, accelerating separation light-induced electrons holes. Therefore, exhibited higher photocatalytic activity than pristine under visible irradiation, including 420, 450, 550, 650 monochromic light, well improved photo-corrosion performance.
