Recently, Chen Haipeng, School of Chemistry and Chemical Engineering, Luoyang Normal University, together with his collaborators, developed a material for high value-added conversion of carbon dioxide, making breakthroughs in the hydrogenation of carbon dioxide to produce low-carbon olefins. Related results were published online in the American Chemical Society "Applied Materials and Interfaces". As one of the greenhouse gases, carbon dioxide is an important indicator of air pollution control. There are three ways to reduce carbon dioxide: the development of new energy sources to replace fossil fuels, the capture and storage of carbon dioxide, and the chemical use of carbon dioxide. Among them, the catalytic conversion of carbon dioxide into low-carbon olefins, low-carbon alcohols, aromatic hydrocarbons and Other high value-added chemicals has been a research hotspot in recent years. Through mechanical force chemical reduction and other methods, the research team designed a magnesium hydride / copper oxide composite material with surface defects. The surface of the material is rich in various types of defective active sites, which can promote the adsorption, activation and hydrogenation of carbon dioxide molecules. In the process of hydrogenation of carbon dioxide, the composite material not only exhibits higher selectivity for low-carbon olefins, but also shows better stability and conversion rate. At the same time, the material can provide a negative valence of hydrogen for hydrogenation of carbon dioxide during hydrogenation, which has an important influence on the choice of hydrogenation reaction path and product distribution. This research provides important theoretical and experimental basis for the design of catalytic materials with high-efficiency carbon dioxide hydrogenation performance.
