3D derived N-doped carbon matrix from 2D ZIF-L as an enhanced stable catalyst for chemical fixation

3D metal N-doped carbon frameworks (M-NCFs) are produced from the direct pyrolysis of 2D zeolitic imidazolate frameworks (ZIF-L Zn and Co) in a reducing atmosphere. The effects of the thermal treatment were studied in order to achieve the desired catalyst. The results show that metal nanoparticles and N-doping species present in the carbon matrix have a direct influence on the catalytic performance. Zn/NCF-1000 displayed quantitative conversion and selectivity towards the chemical fixation of carbon dioxide through the cycloaddition with epoxides. Furthermore, the magnetic property of the newly synthesized Co/NCF-600 was used to demonstrate its superior stability and recyclability, retaining the same catalytic activity for more than 10 cycles.
