First report of a Co based ZIF (ZIF-67) catalyst for the chemical fixation of CO2.
ZIF-67 yields cyclic carbonates at solvent free and co-catalyst free conditions.
The whole process did not use any kind of organic solvents or hazardous halide ions.
ZIF-67 was synthesizable in water at room temperature and exhibits high reusability.
Defects on ZIF-67 external surface supposedly played the key role in catalysis.
