| Abstract: | The fixed bed catalyst of TiO2 bond conjugated with porous silica gel was prepared by an uncomplicated method, the feasibility of photocatalytic degradation of unsymmetrical dimethyl hydrazine (UDMH) using supported TiO2 as catalyst. It was found that the supported catalyst was effective on degradation of UDMH. The effect of adding Cu2 , H2O2 and bubbling air has been studied, which enhanced the degradation rate of UDMH. Moreover, the supported TiO2 catalytic material is very stable mechanically and chemically, and can be used. |
