Abstract

Highlights: [•] Novel Bi2O2CO3/BiOCl nano-composites photocatalysts were synthesized via a facile wet chemical method at room temperature for the first time. [•] The photocatalytic activity was greatly depended on the complex ratio of Bi2O2CO3/BiOCl. [•] The optimal composite Bi2O2CO3/BiOCl (CO3 2−/Cl− =1/6) was obtained and showed greatly enhanced photocatalytic performance than the pure Bi2O2CO3 and BiOCl. [•] The photocatalytic mechanism was ascribed to the dye-photosensitization enhancement by the inner-electric-field in Bi2O2CO3/BiOCl p–n junction. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: In this study, we report controllable synthesis of ZnS–Ag2S composite microspheres by the two-step hydrothermal method, which demonstrate excellent photocatalytic properties. Structure and morphology evolutions are investigated by adjusting the weight ratios of ZnS precursor and AgNO3. Photocatalytic properties of the obtained samples are investigated by the photodegradation analysis of methylene orange (MO) dye. Surface modification of ZnS spheres by Ag2S leads to highly enhanced photocatalytic activity, in comparison to pure ZnS. Furthermore, this method could be extended to prepare other sulfide based composite catalysts. [Copyright &y& Elsevier]
