(ODA)2CuBr4: A stable lead-free perovskite as efficient photocatalyst for dehydrogenative coupling of quinoxalin-2(1H)-ones with amines

Recyclable Copper Indium Sulfide Quantum Dots for Photocatalytic Homocoupling of Arenediazonium Tetrafluoroborates

“…In the past decades, photochemistry has been proved to be an efficient and versatile tool for organic synthesis because of its advantages of simple operation, low energy consumption, environmental friendliness, compatible functional groups, and mild conditions. − Especially, heterogeneous photocatalysis has attracted more and more attention because of its advantages of easy separation and reuse, high thermal stability, and physical and chemical stability. − Among them, cheap and recyclable semiconductors represent an attractive alternative photocatalyst. − CuInS 2 QDs are a direct transition semiconductor with a suitable band gap energy of about 1.53 eV and do not contain any toxic heavy metals. It can provide photoluminescence (PL) emission ranging from the visible to the region, and have broad absorption, large light absorption coefficient, and chemical stability. , Accordingly, CuInS 2 QDs have been successfully applied in numerous fields including water splitting, pollutant degradation, H 2 production, and CO 2 reduction, biological activity .…”
