Illustration of the electrocatalytic conversion of acetylene (C2H2) to 1,3-butadiene (C4H6) on copper catalysts. The process involves the adsorption of acetylene molecules onto the catalyst surface, followed by hydrogenation and coupling of *C₂H₂ and *C₂H₃ intermediates, leading to the formation of 1,3-butadiene, which is subsequently desorbed.
