Abstract:TiO2-WO3 composite catalyst was prepared by Sol-gel method. The photocatalytic activity of the catalyst was investigated for photocatalytic degradation of methyl orange. Synthesis conditions of TiO2-WO3 composite catalyst were optimized by amount of dopped WO3, calcining temperature and time by orthogonal test. Results show that the influencing factors were amount of dopped WO3 〉 calcining temperature 〉 calcining time. Conclusion : The photodegradation activity of TiO2-WO3 with X ( WO3 ) = 2% and calcined at 600℃ for 9 hour is the best.
Keywords:photodegradation  sol-gel method  TiO2-WO3 composite catalyst  orthogonal test
