Lead-free perovskite microcrystals (MCs) have been regarded as promising potential photocatalysts, owing to their high molar extinction coefficient, low economic cost, adjustable light absorption range, and ample surface-active sites. Herein, C-3 thio/selenocyanation of indoles is demonstrated in high selectivity and yield by using lead-free double perovskite CsAgBiBr MCs under visible light irradiation. Moreover, the photocatalyst can be recycled at least 5 times without a significant decrease in catalytic activity.
无铅钙钛矿微晶（MCs）因其高摩尔消光系数、低经济成本、可调节的光吸收范围和丰富的表面活性位点，被视为有前景的潜在光催化剂。在此，通过在可见光照射下使用无铅双钙钛矿CsAgBiBr微晶，吲哚的C-3硫代/硒氰化反应以高选择性和产率得以实现。此外，该光催化剂可循环使用至少5次，且催化活性无显著下降。
