It is generally accepted that methane is a key greenhouse gas that is causing global concern due to climate change. Direct oxidation of methane in the presence of an appropriate catalyst is one of the most renowned procedures for turning methane into value-added products like methanol. In this study, a nanostructured modified Cu-Mordenite zeolite (NF@CuMOR) catalyst was synthesized successfully using hydrothermal and ion exchange techniques. The NF@CuMOR catalyst was characterized by X-ray powder diffraction (XRD) patterns, scanning electron microscope (SEM), transmission electron microscopy (TEM), N<sub>2</sub> adsorption analysis, Fourier-transform infrared spectroscopy (FTIR), and inductively coupled plasma atomic emission spectrometer (ICP-AES). The synthesized NF@CuMOR catalyst exhibited a methanol yield as high as 245 μmol/g-zeolite than unmodified mordenite zeolite (180 μmol/g-zeolite), in the direct oxidation of methane to methanol. High surface area, porosity, and the presence of Cu ions, which served as active sites for the oxidation of methane, were the causes of the high catalytic performance for the creation of methanol. This research may present new potential for improving the catalytic oxidation of methane to make methanol using a NF@CuMOR catalyst.
