摘 要:Largely limited by the high dissociation energy of the O—O bond,the photocatalytic molecular oxygen activation is highly challenged,which re strains the application of photocatalytic oxidation technology for atmospheric pollutants ***,we design and fabricate the InP QDs/g-C_(3)N_(4) *** introduction of InP QDs promotes the charge transfer within the interface resulting in the effective separation of photo-generated ***,InP QDs greatly facilitates the activation of molecular oxygen and promote the formation of O_(2)·under visible-light illuminatio *** conclusions are identified by experimental and calculation ***,NO can be combined with the O_(2)·to form O—O—N—O intermediate to direct conversion into NO_(3).As a result,the NO removal ratio of g-C_(3)N_(4) has a one fold increase after InP QDs loaded and the generation of NO_(2) is effectively *** wo rk may provide a strategy to design highly efficient materials for molecular oxygen activation.
