Facile synthesis of SrNbO2N nanoparticles with excellent visible-light photocatalytic performances

A mild yet facile approach was reported for the synthesis of SrNbO2N nanoparticles via a solvothermal method followed by post-nitridation treatment. The as-resultant SrNbO2N nanoparticles exhibit excellent photocatalytic activity for H2 production (H2 release rate is 148.3 μmol h−1 g−1) and excellent dye degradation efficiency for methylene blue under visible-light irradiation (λ>420 nm).
