Study on Photocatalysis Degradation of Phenol by Using Tourmaline/ TiO2 System as Catalyst
The authors use the method of titanium salts on the surface of tourmaline particles hydrolyzing and coating TiO2 to construct Tourmaline/ TiO2 system in different conditions and characterize the catalyst system by TEM and SEM and Raman Spectra Pattern. The writers used phenol solution as the target compound to observe the removing effects of catalysis system on phenol under dynamic conditions. The results showed that: a. the compound photo catalysis system had brilliant decomposition performance on phenol. b. It would reach high decomposition efficiency on the initial phase of reaction when the rate of tourmaline to TiO2 was 1:1 and the decomposition efficiency could be 96.29% at 120min when the rate was 0.2, which was 26% higher than that of pure phase TiO2.
