Study on Photocatalytic Degradation of MG by PW₁₂-TiO₂/SiO₂

Abstract:

To investigate the photocatalytic degradation of MG by PW₁₂-TiO₂/SiO₂, in this study PW₁₂-TiO₂/SiO₂ composite oxides were prepared by sol-gel and hydrothermal strategy. The prepared photocatalysits were characterized by XRD, BET,TEM and EDS techniques and the configuration charateristics of PW₁₂-TiO₂/SiO₂ nanoparticles were systematically investigated. Photocatalytic activity was checked by the photocatalytic oxidation of MG dye in aqueous solution. The results showed that the phosphotungstic acid still has the Keggin structure. The anatase phase of titanium oxid is identified by XRD. The result of the present work implied that compared with pure TiO₂, the PW₁₂-TiO₂/SiO₂ composite oxides have stronger catalytic activity, good particles dispersion and bigger specific surface area. The optimal concentration of MG was 20mg.L^-1, the best dosage of PW₁₂-TiO₂/SiO₂ was 1g.L^-1. Moreover, after three times of recycling, the catalyst still has high catalytic activity.
