Representative work: Abstract Halide perovskites are excellent catalysts for photocatalytic hydrogen (H 2 ) evolution; however, their instability in aqueous systems limits their applications. In this study, an alternative system is presented to avoid the ionization of halide perovskites based on ethanol splitting and three Bi‐based halide perovskite nanosheets (Cs 3 Bi 2 X 9 PNs; X = I, Br, Cl) are prepared for H 2 evolution. Small amounts of these halide perovskites possess good stability in ethanol, where the optimal Cs 3 Bi 2 I 9 PNs exhibit the highest H 2 evolution rate of 2157.8 µmol h −1 g −1 . In particular, the effects of halogen regulation on the H 2 evolution activity are investigated in depth from va Abstract Photocatalysis is an important technique for synthetic transformations. However, little attention has been paid to light‐driven synergistic redox reactions for directed synthesis. Herein, the authors report tunable oxidation of benzyl to phenylcarbinol with the modest yield (47%) in 5 h via singlet oxygen ( 1 O 2 ) and proton‐coupled electron transfer (PCET) over the photocatalyst Zn 0.5 Cd 0.5 S (ZCS)/graphene oxide (GO) under exceptionally mild conditions. Theoretical calculations indicate that the presence of S vacancies on the surface of ZCS/GO photocatalyst is crucial for the adsorption and activation of O 2 , successively generating the superoxide radical ( • O 2 − ) and 1 O 2
