| Abstract: |
| Photochemical synthesis of the Ag@AgHSiW were characterized by energy dispersive spectrometry (EDS). The procedure of the Ag@AgHSiW synthesis and the visible light photocatalytic degradation of methylene blue (MB) were measured with the ultraviolet visible absorption spectrometry. Finally，the mechanism for the enhancement of photocatalytic activity of the Ag and heteropolyanion were discussed． |
