Biotemplates are often used in the preparation of catalysts due to availability of raw materials and environment-friendly. Herein, three biomorphic CeO2 were prepared from waste tobacco materials and impregnated with 1 wt% Ru for the catalytic combustion of vinyl chloride. The results showed that the biotemplates greatly affected the properties of the catalysts. 1Ru/CeO2-YS exhibited the best catalytic activity and superior stability because of its abundant oxygen vacancies, sufficient acidic sites and the optimal redox properties. SEM images suggested that CeO2-YS and CeO2-YM maintained the basic structure of the biotemplates. Moreover, a possible reaction mechanism over Ru/CeO2 was proposed.
