摘　　要：Formaldehyde(HCHO) emitted from chemical manufacturing plants including methanol-gasotine/ diesel fuel vehicles and the construction and decoration materials is one of the major air pollutions,which induces photochemical pollution and hazards human health.Great efforts have been made for the reduction or control of the emission of HCHO to satisfy the stringent environmental regulations.Now,a new study supported by the National Natural Science Foundation of China reports mesoporous manganese oxide with novel nanostructures for the decomposition of HCHO.The obtained manganese oxide nanomaterials showed high catalytic activities for oxidative decomposition of HCHO at low temperatures.Complete conversion of HCHO to CO_2 and H_2O were achieved,and no harmful byproducts were detected in effluent gases.The catalytic activities of these nanomaterials are significantly higher than those of previously reported manganese oxide octahedral molecular sieve(OMS-2) nanorods,MnO_x powders,and alumnina-supported mangnaese-palladium oxide catalysts.These results provide a new route for the removal of HCHO and other air pollutions. 关键词：甲醛完全氧化低温国家自然科学基金光化学污染排放控制业务管理系统二氧化锰
