Lead-free perovskite Cs3Bi2Br9/TiO2 composites for atmospheric photocatalytic oxidation of sulfides†
Photocatalytic selective oxidation represents an eco-friendly strategy for chemical transformation. Herein, a lead-free halide perovskite Cs3Bi2Br9 combined with TiO2 was facilely synthesized and applied for efficient photocatalytic selective oxidation of sulfides to sulfoxides with high yields and good compatibility under mild conditions. The Cs3Bi2Br9/TiO2 composite exhibited enhanced photocatalytic activity compared to bare Cs3Bi2Br9 particles, which could be ascribed to the strong interaction between Cs3Bi2Br9 NCs and TiO2 markedly accelerating the separation and transfer efficiency of photogenerated electron–hole pairs and simultaneously suppressing their recombination.
期刊介绍：
Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
