This invention discloses a plasma-coupled electrocatalytic carbon dioxide conversion device and method with product phase separation. Carbon dioxide gas forms non-thermodynamically equilibrium active carbon dioxide excited-state particles under the action of dielectric-barrier plasma discharge, effectively breaking high-energy carbon-oxygen bonds. These active particles are then converted into gaseous-liquid carbon products under the electrocatalytic action of a catalyst-loaded gas diffusion electrode. The gaseous products are directly discharged from the outlet, while the liquid products are briefly stored in a three-dimensional additively manufactured porous channel layer between the ion exchange membrane and catalyst layer for enrichment. The liquid products are then discharged and collected via a pulsed water circulation system. The high-concentration, low-impurity liquid products are easily utilized downstream. This invention features a flexible, convenient, modularly integrated, and environmentally friendly device, achieving efficient zero-carbon conversion of carbon dioxide throughout the entire process and a multiphase physical field design for multiphase carbon dioxide conversion.
