Synthesis and Photocatalytic Application of Mn3O4/CdS Composite

Abstract:

In this work, CdS nanosheets were synthesized by microwave hydrothermal method. We used a simple synthesis method to prepare Mn3O4/CdS composites. The crystal phase, surface chemical component and optical properties of Mn3O4/CdS, Mn3O4 and CdS were analyzed based on the characterizations such as XRD, FT-IR, DRS and PL. Mn3O4/Cd composites showed obvious broadened visible-light adsorption at wavelength over 460 nm. When the mass ratio of Mn3O4 and CdS was 1.0%, Mn3O4/CdS displayed the best RhB degradation efficiency which was 22.39% higher than the pure CdS. The improved photocatalytic efficiency should be attributed to the lower photo-induced electron–hole pair recombination rate and accelerated transfer rate of photogenerated electrons based on heterojunction structure. The achievements provided new way to exploring novel CdS-based heterojunctions for decomposing organic pollutants.
