| Abstract: | The TiO2 /attapulgite nanocomposites were prepared by LTDRP technique with attapulgite as the supports,and TiCl4 as the titanium.The photocatalytic degradation process of methylorange on the composites was studied under different conditions.The results show that the degradation rate of photocatalytic methyl orange is about 93.75%for 4h when the amount of catalyst is 1.0g/L and initial concentration of methyl orange is 0.01g/L in the pH=3 solution.The kinetics of photocatalytic degradation reaction can be ex... |
