Bipolar ethylene electrosynthesis from CO₂ and biowaste acid with total faradaic efficiency over 118.

ABSTRACT: Ethylene (C₂H₄), a cornerstone of the chemical industry, is produced predominantly via fossil-intensive high-temperature processes that contribute significantly to global energy consumption and CO₂ emissions. Here, we report an ambient bipolar C₂H₄ electrosynthesis system that concurrently decarboxylates propanoic acid, a prevalent biorefinery waste, at nanoporous Pt microparticles-coated anode and reduces CO₂ at W-doped CuO_x-loaded cathode. Physicochemical and operando spectroscopy characterizations, along with theoretical modeling reveal that the polarized Pt-PtO₂ interface formed in situ downshifts the d-band relative to Fermi level which favors the desorption of *CH₂CH₂ interme
