Photocatalytic oxidation of methanol selectivity in the preparation of the application of methylformate

In order to improve the application performance of methanol selective photochemical oxidation in the preparation of methyl formate, the catalytic performance of different oxides was analyzed. A series of TiO2 catalysts supported by gold, silver and copper were synthesized by the method of metal sol deposition. The catalytic properties of different oxides were analyzed. The most appropriate amount of methanol was selected to explore its application in the preparation of metal formate. The effects of temperature, load, space velocity and other factors on the catalytic properties were explored through experiments. By comparing the catalytic performance of different oxides, it is found that when the oxides are CH3OH, the prepared CH3OH / MoO3-SnO2 has better catalytic effect. Therefore, the catalyst with good dispersion and suitable acid-base position is more favorable for the formation of methyl formate and the conversion of methanol.
