| Abstract: |
| A new complex heteropoly acid,H4SiW12O40/TiO2,was prepared by immersion method,and then characterized with XRD,FTIR and UV-Vis techniques.By means of this catalytic material,the optimum photocatalytic conditions of photocatalytic activity for oxygen evolution have been studied.The results show that the H4SiW12O40/TiO2 still reserved the Keggin structure.A physical adsorption existed between H4SiW12O40 and nanosized titania.In the experiment of water splitting to oxygen under UV-illuminated condition,the rat... |
