The indirect transformation of methane to generate chemicals has been used in industrial production,and the direct way is being developed to realize large- scale production as soon as possible. The research background of catalysts for the direct oxidation of methane at home and abroad was briefly described. Attention was paid to the present research status of catalysts for the direct oxidation of methane to alcohol and aldehyde,and the research progress of catalysts for the direct oxidation of methane in several new fields was analyzed,such as novel nano- structured catalyst,microwave- assisted catalytic conversion and ionic liquid- based reaction system. Moreover,the application prospects of catalysts for the direct oxidation of methane were also discussed.
