TiO2/α-Al2O3is prepared by liquid-phase deposition method from titanium ammonium fluoride. The morphography and crystal form of supported catalyst are analyzed by XRD and SEM. The results show that anatase is detected when the calcination temperature is 800°C, the interaction of TiO2and support inhibit TiO2transfer into anatase. The addition of polyvinyl alcohol makes the active component evenly distributed. It is found that when support for catalyst is honeycomb column α-Al2O3, loading amount is 4.0%, and calcination temperature is 800°C, the CODcr removal rate could reach 66%. Furthermore, no obvious evidence of deactivation and intensity for the catalyst could be seen after running for 100 hours.
