摘要：

RuO2/TiO2 coupled photocatalyst was prepared by sol-gel-dipping method. Being a model reaction, the photocatalytic degradation of direct fast black G was investigated in RuO2/TiO2 powder suspension irradiated by UV-lamp. The results showed that the addition of RuO2 to TiO2 greatly enhanced its photocatalytic activity, and the optimum dipped content of RuO2 was 0. 16%, the optimum value of the calcinations temperature and the addition of RuO2 /TiO2 powder were 500 degrees C and 5. 00 g.L-1, respectively. The photocatalytic degradation of direct fast black G was experimentally demonstrated to follow the Langmuir-Hinshelwood kinetic model, and the adsorption constant ( 14.22 L.mmol(-1)) and the reaction rate constant [4.94 x 10(-3) mmol(L.min)(-1)] were determined, respectively.
