英文摘要：

The progresses in three ways for direct oxidation of methane to methanol by molecular oxygen, including gas phase oxidation, liquid phase oxidation and plasma conversion, were reviewed. For the gas phase reaction and liquid phase reaction, the effects of catalyst on the reaction performances of methane to methanol were discussed. For the cold plasma reaction, the research results on single cold plasma reaction and cold plasma-catalytic oxidation reaction were described. Based on the current researches, the future research directions for this reaction was pointed out.
