Methanol is a kind of important basic chemical raw material. With the increase of global methanol production capacity, the catalytic conversion of methanol to methanol downstream high value-added downstream products is very important. The bifunctional catalysts for one-step oxidation of methanol to dimethoxymethane (DMM) and methyl formate (MF) with high value-added are very useful and have received considerable attention. In this paper, the recent applications of bifunctional catalysts for one-step oxidation of methanol to DMM and MF in recent are reviewed and summarized. The catalysis of bifunctional catalysts and the distribution of the products, especially the precious metal catalysts, metal oxide catalysts and heteropolyacid catalysts are carefully analyzed in order to provide a wide range of references for the catalytic conversion of methanol through synthesis step process of DMM and MF.
