Optimizing photo-oxidation of alcohols to aldehydes: a study on the high-performance photocatalytic activity of methylene blue

This research investigates methylene blue as a high-performance photocatalyst in the photo-oxidation conversion of alcohols to aldehydes. The present study investigates the optimal conditions for the solvent effect, catalyst, and oxidant amount. The objective is to identify the most practical combination of these factors to optimize the desired outcome of the experiment. The notable characteristics of this transformation include its gentle conditions, the use of a metal-free organic dye as a photocatalyst, and TBHP’s dual function as both a radical initiator and a means for regenerating the photocatalyst. This research provides valuable insights into the potential of methylene blue as a high-performance photocatalyst in the photo-oxidation reaction of alcohols, paving the way for more efficient photocatalytic processes.
