Liquid Metal Catalysis

With the rapid growth of the world population and the continuous shortage of resources and energy, the research on liquid metal catalyst has gradually come into view. In recent years, the development of liquid metal and its alloys as new catalysts has made a great leap forward. Liquid metals as flow catalysts offer new research and development opportunities. Applications of liquid metal systems include the catalytic controlled growth of graphene, the catalytic growth of 2D materials (MoO2, MoS2, SnOx, etc.), the catalytic reduction of CO2 to achieve carbon neutrality, the catalytic organic and inorganic reactions (including propane dehydrogenation, methane dehydrogenation, polyphenol self-polymerization, free radical polymerization, etc.), and the catalytic production of hydrogen. Liquid metal catalysts also include photocatalysts, electrocatalysts, bimetallic catalysts, LM/MO frame catalysts, and heterogeneous catalysts. The classification, application, and related catalytic mechanism of different liquid metal catalysts at home and abroad were reviewed in this chapter. Liquid metal catalysts could be used as revolutionary materials in the new century, and their application in the field of catalysis presents new challenges.
