Electrocatalysis The Ru complex is set on its path, along which it must cross either a high mountain (EEC pathway) or a smaller hill (ECE pathway) to reach the glittering green palace where it can fulfill its goal of converting CO₂ to CO. The sun shines brighter on the ECE path, which is alluring and less energy-demanding. The complex can tread that path provided that its Ru heart has electrons (e⁻) pumped in (tBu on terpyridine), and that the CH₃CN is easily removed. This is achieved by a CH₃ group at the bipyridine, which pushes the bipyridine into the CH₃CN with the force of a bull, thereby facilitating CH₃CN dissociation from the complex. More information can be found in the Full Paper by S. Ott, S. Maji et al. on page 14870 ff.
