| Abstract: | the nano-TiO2 wrapped by SnO2 was prepared by the method of deposition- uniformity, the photocatalytic activities was tested and analysed through XRD, FTIR, GC-MS and study on coking-waste-water treated by photocatalytic oxidation. Practice shows that SnO2 can be used to wra PTiO2 in order to improve the photocatalytic activities of titanium, and only when the TiO2 wrapped by more than 5 % SnO2, the enhancement of photocatalytic activities is remarkable. |
