CH4 conversion to value added products has got environmental and economic importance. Its conversion to acetic acid is being challenge due to its high activation energy. Hence, the kinetic and mechanistic information are the significant in activating CH4 especially to acetic acid. In this article, these parameters are studied by carbonylating CH4 using CO2. For the study, different redox catalysts were prepared varying their redox properties and atomic size. Various techniques like solid state NMR, XRD, Raman, BET, XPS, TGA and FT-IR were helped in deducing the mechanistic steps. Concept to apply Langmuir-Hinshelwood theory of gas adsorption by providing dual active sites for two different gases worked well yielding higher concentration of acetic acid.
