WebApr 11, 2024 · For the reaction of CO 2 to HCHO via the four-electron pathway, the reaction follows the two-electron pathway except for the CO desorption process. The hydrogenation of *CO to *CHO in the four-electron pathway is slightly easier than the CO 2 hydrogenation to *COOH step, and the energy barriers for *CO reduction to *CHO are 0.38 eV on Cu (110 ... WebReaction path A transition structure is of course a maximum on the reaction pathway. One well-defined reaction path is the least energy or intrinsic reaction path (IRC). Quasi-Newton methods oscillate around the IRC path from one iteration to another and several groups have proposed methods for obtaining the IRC path from the quasi-
