Application of Biobased Catalysts in Chemical Conversion of CO2

CO(2 )is the most abundant C1 platform compound on earth, characterized by non-toxicity, renewability, chemical stability, and availability. Therefore, it is of great significance to convert CO2 into high value-added chemicals through chemical conversion. Due to the high thermodynamic stability and kinetic inertness of CO2, most chemical conversion reactions require the use of high-efficiency catalysts. So far, various catalytic systems have been developed, such as porous carbon, ionic liquids (ILs), covalent organic frameworks (COFs), porous organic polymers (POPs), and metal organic frameworks (MOFs). Although these catalysts have high catalytic activity, they also have many drawbacks, namely, the source of raw materials is not wide, and most of these raw materials are not renewable, and the preparation process of these catalysts is not green. Therefore, it is particularly important to prepare renewable catalysts using small natural molecules or natural polymers as raw materials. The research progress of catalytic systems containing natural products, such as amino acids, choline derivatives, cellulose, chitosan, lignin, etc., is summarized in the preparation of high value-added chemicals from CO2.
