The heterostructure Ag@WO 3– x ( x =0.1 or 1) composites with high selectivity for breaking azo-bond were obtained by in situ reduction of Ag 2 WO 4 . The crystal structure and morphology of Ag@WO 3– x were characterized by X-ray powder diffraction(XRD), scanning electron microscope(SEM) and transmi...
