Abstract: This paper briefly reviews the advance in the synthesis of methanol from methane via partial oxidation and the synthesis of methanol from halogenated methane. The heterogeneous oxidation from methane to methanol by molybdenum-based catalyst has a wide perspective of application. By using Pt or Pd complex as catalyst in aqueous homogenous system, methane is converted to methanol with high conversion and selectivity, but the high cost of catalyst, rigorous conditions and serious pollution to the environment prohibit its widespread use. In the gaseous homogenous system under high temperature and pressure, the structure of reactor is very complicated. Although the special enzyme has effective performance, its study is still in the lab due to the difficulty in the preparation of enzyme. It is very interesting that photocatalysis of methane has good prospect in terms of environmental protection, however, the main drawback is the development of novel, highly efficient catalysts. The route from methyl halide to methanol with high conversion and selectivity has unique advantages in methane activation, and attracts close attention in basic and applied research.
