Preparation of TiO2-ZnO and its activity test in sonophotocatalytic degradation of phenol

Synthesis of TiO2-ZnO and its activity test in Sono photocatalysis degradation of phenol has been conducted. The synthesis was performed by the sol-gel mechanism by using titanium isopropoxide and zinc acetate as precursors with the Ti: Zn ratio of 5:1. Characterization of material were conducted by x-ray diffraction analysis, surface area analysis and also diffuse reflectance UV-Visible spectrophotometry. The material obtained from the synthesis was tested in photocatalysis, Sono catalysis and Sono photocatalysis degradation of phenol solution. Results showed that material exhibited the activity of varied mechanism o-phenol degradation. In advance, the Sono photocatalysis degradation produced the synergy index of 1.169 compared to both photocatalysis and Sono catalysis.
