Abstract:

Natural gas is rich in reserves and is increasingly becoming one of the important clean energy, and the synthesis of high value-added compounds from its main component methane is the frontier of research. Because the structure of methane is stable and the energy of CH bond is very high, the conditions for activating methane are very harsh. In this paper, the reaction principle, research progress, catalytic reactors and shortcomings of common photocatalytic oxidation of methane to compounds are introduced, and then the reaction principle, research progress and catalytic reactors of laser catalytic oxidation of methane to compounds are reviewed. Pointed out that laser light source has many advantages, such as improving the quantum efficiency of photocatalyst and shortening the reaction time of photocatalysis. Then on the basis of in-depth study of the mechanism of laser catalytic reaction, it is expected to significantly improve the performance of laser catalytic reaction, including methane oxidation through designing the scientific and reasonable laser reaction system and selecting the efficient photocatalysts, which has important academic significance and practical value. In the future, the key research direction is to activate methane under mild conditions and to synthesize high value-added compounds by laser catalytic oxidation.
