Abstract Industrial production of H 2 O requires lots energy and causes environmental pollution. Moreover, in subsequent applications, much economic loss could be produced during the transportation process its dilution process. Therefore, it is highly desirable for situ application . In recent years, catalytic synthesis , e. g., direct synthesis, electrocatalytic photocatalytic has attracted more attention because continuous low‐concentration by can directly used oxidation organic compounds, effectively avoiding shortcomings current industrial route. Here, we briefly reviewed latest processes via various routes. On this basis, summarized discussed typical conversion reactions, including ammoximation ketones, alcohols, C−H bonds, olefins. Some coupling reactions have shown excellent performance with high selectivity, cost been significantly reduced. Finally, utilization were analyzed, some strategies promoting efficiency proposed.

Abstract Plastic pollution constitutes an evergrowing urgent environmental problem, since overaccumulation of plastic waste, arising from the immense increase production disposable products, overcame planet's capacity to properly handle them. Chemical upcycling polystyrene a convenient method for conversion waste into high‐added value chemicals, suggesting attractive perspective in dealing with crisis. We demonstrate herein novel, easy‐to‐perform organocatalytic photoinduced aerobic protocol, which proceeds via synergistic indirect hydrogen atom transfer (HAT) catalysis under LED 390 nm Kessil lamps as irradiation source. The developed employs BrCH 2 CN‐thioxanthone photocatalytic system and was successfully applied variety everyday‐life leading isolation benzoic acid after simple base‐acid work up yields varying 23–49 %, while large‐scale experiment performed, that step is susceptible industrial application.
