Abstract

Highly active CuO-CeO₂-ZrO₂ catalysts were prepared by sol-gel method, using environmentally friendly bacterial cellulose (BC) as structure directing regent.
The catalyst designed with commercial BC (Com-BC) exhibited catalytic performances in toluene (T100 =220 ^oC) and ethyl acetate oxidation (T100 =170 ^oC) superior to the catalysts prepared by traditional methods. Furthermore, excellent stability was obtained and no deactivation was observed during the 100 h on stream in toluene and ethyl acetate oxidation at T100. The excellent activity and stability of Com-BC can be explained by the hierarchically porous structure, abundant oxygen vacancies, and good reducibility.
