Formaldehyde（HCHO）is carcinogenic and teratogenic,and is therefore a serious danger to human *** also adversely affects air *** oxidation is an efficient technique for removing *** development of highly efficient and stable catalysts that can completely convert HCHO at low temperatures,even room temperature,is *** Pt and Pd catalysts can completely convert HCHO at room temperature,but their industrial applications are limited because they are *** catalytic activities in HCHO oxidation of transition-metal oxide catalysts such as manganese and cobalt oxides with unusual morphologies are better than those of traditional MnO2,Co3O4,or other metal *** is attributed to their specific structures,high specific surface areas,and other factors such as active phase,reducibility,and amount of surface active *** catalysts with various morphologies have great potential and can also be used as catalyst *** loading of relatively cheap Ag or Au on transition-metal oxides with special morphologies potentially improves the catalytic activity in HCHO removal at room *** preparation and development of new nanocatalysts with various morphologies and structures is important for HCHO *** this paper,research progress on precious-metal and transition-metal oxide catalyst systems for HCHO oxidation is reviewed; topics such as oxidation properties,structure–activity relationships,and factors influencing the catalytic activity and reaction mechanism are *** prospects and directions for the development of such catalysts are also covered.
