A research group led by Prof. Junji Nakamura (Green hydrogen production and utilization) has proposed a potential diagram of the CH₃OH synthesis via H₂COO_a from CO₂ on Cu surfaces, with the aid of density functional theory calculations and literature data, in which the hydrogenation of bidentate HCOO_a to H₂COO_a is potentially the rate-determining step and accounts for the apparent activation energy of the methanol synthesis from CO₂ on Cu surfaces.
