A Bifunctional Turigstate Catalyst for Chemical Fixation of CO2 at Atmospheric Pressure

摘要

Chemical fixation of carbon dioxide (CO2) into useful and valuable chemicals is a key technology for sustainable low-carbon society because CO2 is a renewable and environmentally friendly C1 source, which is in contrast to toxic CO and phosgene. However, CO2 is much less reactive than CO and phosgene, and a large energy input (e.g., highly reactive reagents, high pressures of CO2, and stoichiometric amounts of strong acids or bases) is usually required to transform CO2 into various chemicals. Therefore, the low-energy catalytic fixation of CO2 is highly desirable. Catalytic CO2 fixation at atmospheric pressure has been limited to reactive substrates (strained cyclic molecules, unsaturated compounds, etc.), and bifunctional catalysts, which allow a concerted action on both CO2 and substrates, are promising candidates for highly efficient CO2 fixation at atmospheric pressure.
