However, a groundbreaking approach is presented by introducing a high\u2010entropy\u2010based material for CO\n                    <jats:sub>2<\/jats:sub>\n                    \u00a0reduction to methanol (CH\n                    <jats:sub>3<\/jats:sub>\n                    OH). This method offers scalability and simplicity, making it feasible for large\u2010scale production of high\u2010entropy\u2010alloys (HEAs). The formation of HEA is facilitated by the presence of Fe, leads to the creation of a high\u2010entropy oxide (HEO) during calcination. Through X\u2010ray photoelectron spectroscopy (XPS) and X\u2010ray absorption spectroscopy (XAS), comprehensively analyzed the oxidation states and coordination environments of all metals in both HEO and HEA. The formation of Fe\n                    <jats:sub>3<\/jats:sub>\n                    O\n                    <jats:sub>4<\/jats:sub>\n                    \u00a0within the HEO structure is evident, with each metal occupying either tetrahedral (T\n                    <jats:sub>d<\/jats:sub>\n                    ) or octahedral (O\n                    <jats:sub>h<\/jats:sub>\n                    ) sites. The HEA formed shows exceptional CO\n                    <jats:sub>2<\/jats:sub>\n                    \u00a0conversion efficiency and higher CH\n                    <jats:sub>3<\/jats:sub>\n                    OH selectivity. Isolated sites of Co, Ni with Fe, Cu, and Zn, along with CuZn pair, are considered as the active sites for CO\n                    <jats:sub>2<\/jats:sub>\n                    to CH\n                    <jats:sub>3<\/jats:sub>\n                    OH and further determined by DFT calculations. The altered reaction mechanism upon HEA formation compared to individual metals is investigated using in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). Finally, Life\u2010cycle assessment (LCA) indicates the carbon\u2010negative footprint.\n
