Constructing a novel ternary composite Co-doped CdSe loaded on biomass carbon spheres as visible light photocatalysts for efficient photocatalytic applications

Abstract

The Co-CdSe/BCS photocatalyst are facily prepared by a transitory hydrothermal reaction of 40 min. The Co-CdSe/BCS photocatalyst is constructed via the In-situ growth of Co-CdSe nanodots on the surfaces of the biomass carbon spheres (BCS). Doped Co2+ would generate electron trap which can capture the photoinduced electrons, resulting in the efficient separation of photoinduced electron-hole pairs. Furthermore, the introduction of carbon spheres can enhance the optical absorption property and electron transport ability. Electrochemical characterization and PL spectra demonstrate the Co-CdSe/BCS is able to efficiently separate electron-hole pairs and inhibit their recombination. The as-synthetized samples diaplay the high efficiency for the photodegradation of the Methylene blue (MB) dye under visible light. This study offers a new strategy to promote photocatalytic performance of CdSe photocatalyst.
