A new and efficient iron‐based photocatalyst has been developed via covalent grafting of the iron ascorbic acid complex on TiO 2 nanoparticles. The obtained nanomaterial was characterized by FT‐IR, TGA, XPS, TEM and ICP‐AES. The photocatalytic activity of the resulting nanocatalyst was demonstrated under visible light irradiation in the selective aerobic oxidation of benzyl alcohols and benzylic hydrocarbons in ethyl acetate. Further, visible‐light‐driven oxidation of olefins and sulfide in the presence of TBHP successfully occurred producing the corresponding epoxides and sulfoxides in high yields and excellent selectivity. The stability of the catalyst toward leaching and its reusability renders the present strategy practical to address the environmental and industrial issues.
