A high active novel TiO₂/AC composite photocatalyst was prepared and used for phenol degradation. It was much more active than P-25 and exhibiting good decantability, less deactivation after several runs and less sensitive to pH change. Diffuse reflectance spectra (DRS)revealed that the electronic change in TiO₂ did not occur by the addition of AC. Results of SEM and XRD suggested that better TiO₂ distribution can be achieved when optimal AC content was adopted. The performance of the prepared TiO₂/5AC catalyst revealed great practical potential in wastewater treatment field.
