Experimental Research on Preparation of Complex Optical Catalyst of TiO2/Rectorite and Its Catalytic Decomposition on Acidic Fuchsine

The paper has reported the synthesis of TiO 2/rectorite multiplex photo-catalyst and the photocatalytic degradation of acid fuchsine.The discoloring ratio of acid fuchsine can be as high as 91.7% in 2 hours degradation.The experiments show that the composite temperature and the roasting temperature are the main factors, which influences on the degradation efficiencies. With application of the TiO 2/rectorite multiplex photo-catalyst,the added quantity and the value of pH also affect the degradation efficiencies.Further more, the regenerated efficiencies of the regenerated photo-catalyst is as better as the original one.
