Effects of microporous layer on electrolyte flooding in gas diffusion electrodes and selectivity of CO₂ electrolysis to CO

Understanding the relationship between gas diffusion electrode (GDE) structures and the performance of electrochemical CO₂ reduction reaction (CO₂RR) is crucial to developing industrial-scale technologies to convert CO₂ to valuable products. We studied how the microporous layer (MPL) on GDE's coated with...

Anisotropic proximity-induced superconductivity and edge supercurrent in Kagome metal, K_1-xV₃Sb₅

Materials with Kagome nets are of particular importance for their potential combination of strong correlation, exotic magnetism, and electronic topology. KV3Sb5 was discovered to be a layered topological metal with a Kagome net of vanadium. Here, we fabricated Josephson Junctions of K1-xV3Sb5 and induced superconductivity over long junction...

Urea-Functionalized Silver Catalyst toward Efficient and Robust CO₂ Electrolysis with Relieved Reliance on Alkali Cations

We report a new strategy to improve the reactivity and durability of a membrane electrode assembly (MEA)-type electrolyzer for CO2 electrolysis to CO by modifying the silver catalyst layer with urea. Our experimental and theoretical results show that mixing urea with the silver catalyst can promote electrochemical CO2 reduction (CO2R),...

The role of electrode wettability in electrochemical reduction of carbon dioxide

The electrochemical reduction of carbon dioxide (CO₂RR) requires access to ample gaseous CO₂and liquid water to fuel reactions at high current densities for industrial-scale applications. Substantial improvement of the CO₂RR rate has largely arisen from positioning the catalyst close to gas-liquid interfaces,...
