Phenol photocatalytic degradation over Fe-TiO2 materials synthesized by different methods

The photocatalytic activity and stability of 3% Fe-TiO. materials synthesized by incipient wet impregnation (% Fe-TiO.-DP25) and sol-gel (3% Fe-TiO.-sol-gel) were studied using the phenol degradation as test reaction. The effects of various operation parameters including photocatalyst concentration,...
