“…CO 2 is a non-toxic, renewable, inexpensive, and abundant raw C1 feedstock, and it can act as a C1 building block for the synthesis of various valuable chemicals with added economic value, such as carbonates, carbamates, urea, etc. 4–7 Different types of catalysts can be designed for this purpose, like porous organic polymers (POPs), metal organic frameworks (MOFs), covalent organic frameworks (COFs), oxide-based compounds, ionic liquids, etc. 4–9 The designed catalysts should be selective, stable, easily recoverable from the reaction medium, durable, and highly efficient for industrial applications.…”
