Global warming has been growing due to worldwide industrialization, misbalancing contents of natural gas. Methane (CH4) involves faster than CO2 in global warming process. Hence, current main strategy is to utilize CH4 gas as major feedstock to produce industrially most important chemicals such as methanol, acetic acid and etc. Activating CH4 has been challenging for catalytic science as it requires high activation energy. Here in this work we have tailored properties of the catalyst for CH4 conversion providing acidity, N-O denting ligands, and noble metal for catalysis. The catalyst was prepared from D-glucosamine with silver chelation, and was confirmed by XRD, FT-IR, XPS, TEM, and SEM-EDX. The catalyst produced 175 µmoles of methanol when 0.15g of catalyst in each case was used at 30 bar pressure. With the addition of halide ion containing molten salts as reaction promoter, 11 times higher conversion of methane was archived.
