  • Nanocatalyst for partial oxidation of methane, method for preparing the nanocatalyst and method for partial oxidation of methane using the nanocatalyst
    Patent number: 11878295
    Abstract: A nanocatalyst for partial oxidation of methane is disclosed. The nanocatalyst is prepared by carbonizing a metal-organic framework coordinated with copper ions to form a structure in which nitrogen atoms present in a nitrogen-doped porous carbon structure form coordinate bonds with copper ions. This structure enhances the chemical stability of the nanocatalyst, prevents the peroxidation of methane at low temperature, and significantly improves the conversion efficiency of methane to liquid products such as methanol and methyl hydroperoxide by selective partial oxidation of methane gas. Also disclosed are a method for preparing the nanocatalyst and a method for partial oxidation of methane using the nanocatalyst.
