- Abstract
- Here, we disclose carbon-based Co catalyst obtained by the controlled thermal decomposition of 2D MOF: Co-ZIF-L. The latter is compared to the more conventional ZIF-67 which was already studied for CO2 methanation[7]. Here, Co(NO3)2 and 2-methylimidazol are applied to synthesize the MOFs via ultrasonication (Co-ZIF-L) and at room temperature (ZIF-67). The resultant powders after drying are carbonized at 800°C under Ar to form Co nanoparticles dispersed in porous carbon (CoNP-C). CO2 methanation is performed in a fixed bed flow reactor with 100 mg of the catalyst while the molar ration H2/CO2= 4/1, the GHSV=24000 ml/gcat.s and P=0.1MPa . Importantly, with this catalyst the reduction step with hydrogen is skipped since CoNP are formed during the carbonization.
