| Abstract: | The solid material H3PW12O40/ZrO2 was prepared by the sol-gel and wet impregnateion method. ICP-AES, Infrared （IR）speetra, N2 adsorption and thermogravimetry （TG） analysis were used to characterize the composition, structure and surface physieoehemieal properties of the as-prepared solid photoeatalytie material. The results indicated that the composite retained the Keggin structure. Moreover, the composite exhibited nanoporous structures. |
