Transition metals (group VIII) like cobalt (Co), iron (Fe), nickel (Ni), and ruthenium (Ru) have been identified as being effective catalysts for several reactions. It would be ideal to create a different technique for making highly active metal catalysts with the appropriate porous structure and enhanced active metal dispersion. Metal organic frameworks (MOFs) are a class of microporous crystalline polymers made up of a metal and an organic ligand. They have a high surface area and porosity and can be used in a wide range of applications, including gas storage and separation, chemical sensing, heterogeneous catalysis, bioimaging, drug delivery, and luminescence. When the pyrolysis circumstances are ideal, the reducibility of cobalt nanoparticles can be further improved. High metal loading, effective active phase dispersion, and encapsulation produce a very high activity and strong stability. One of the most popular MOFs employed in this context is the nitrogen-rich ZIF-۶۷ due to its unique properties. They produce carbon-encapsulated cobalt nanoparticles when pyrolyzed in an inert atmosphere, which prevent the production of larger agglomerates and favour the dispersion of cobalt particles. In the presented research, along side carbonization temperature, plasma treatment effect on the catalyst characteristic was studied.
