摘　　要：A catalytic reaction over a silver catalyst performed in an unregarded temperature region（473-873 K） with a long catalytic lifetime for the production of methyl formate from methanol was provided as a potential preparing route. The optimal yield of methyl formate（ca. 14. 8% ） with a selectivity 〉90% was obtained at about 573 K. Because α- oxygen species and bulk oxygen species coexist in the unregarded temperature region, a synergistic process concerning α-oxygen species and bulk oxygen species was proved over Oα -rich and Oγ-rich samples.A catalytic reaction over a silver catalyst performed in an unregarded temperature region（473-873 K） with a long catalytic lifetime for the production of methyl formate from methanol was provided as a potential preparing route.
