Air atmospheric photocatalytic oxidation by ultrathin C, N-TiO2 nanosheets

Herein, we demonstrate the highly efficient photocatalytic sulfide oxidation reaction under mild conditions, i.e. in air, at room temperature and in the absence of a sacrificial reagent, co-catalyst or redox mediator, by using ultrathin C,N-TiO2 nanosheets as a photocatalyst.
