TiO₂/AC(ω(AC)=5%) composite photocatalysts prepared via TiCl₄ hydrolysis method were calcinate at different temperatures.XRD,DRS,FTIR,SEM and N₂ adsorption isotherm were used for crystal structure,spectral characteristics and surface properties measurement.Phenol was used as a probe compound for the photocatalytic activity test.Effect of activated carbon modification on the structure chracteristics and photocatalytic activity of TiO₂ photocatalyst was investigated.The results show that TiO₂/AC exhibits a higher activity than TiO₂ within a wide range of calcination temperatures.AC was beneficial to TiO₂ size control and phase transformation retardment.
