Abstract Achieving satisfactory multi-carbon (C 2+ ) products selectivity and current density under acidic condition is a key issue for practical application of electrochemical CO 2 reduction reaction (CO RR), but challenging. Herein, we demonstrate that combining microenvironment modulation by porous channel structure intrinsic catalytic activity enhancement via doping effect could promote efficient RR toward C in electrolyte (pH ≤ 1). The La-doped Cu hollow sphere with channels exhibits Faradaic efficiency (FE) 86.2% partial −775.8 mA cm −2 . single-pass conversion can reach 52.8% at −900 Moreover, the catalyst still maintains high FE 81.3% −1 A plays crucial role accumulating K + OH - species near surface within channels, which effectively suppresses undesired hydrogen evolution promotes C–C coupling. Additionally, La enhances generation *CO intermediate, also facilitates formation.

Abstract CO 2 electroreduction (CO RR) to high‐value chemicals by renewable energy is a promising route for achieving carbon cycling. Traditional two‐dimensional planar electrodes applied in RR are faced with problems of high mass transfer resistance, carbonate precipitation, flooding, and complicated structures, seriously limiting their efficiency application. Three‐dimensional hollow fiber gas diffusion (HFGDEs) candidates due rich specific surface area, low simplified component, no flooding trouble, which beneficial current density as well efficiency. In this review, we provide inspirations positive paradigms the rational design HFGDE toward following part: 1. The mechanism RR. 2. classification typical metal‐based catalysts. 3. preparation process HFGDEs. 4. Recent advanced studies 5. Challenges at stage future development HFGDEs towards accelerating application industrial reduction electrolyzers.

The acidic electroreduction of CO2 into multicarbon (C2+) products is much attractive for the improved carbon utilization than alkaline or neutral electroreduction. How to improve efficiency C2+ generation by CO2, important, especially at high current density and in electrolyte with low K+ concentration. Herein, we propose a strategy capping Cu surface polymeric ionic liquid (PIL) adlayer boosting electrocatalytic conversion densities (ampere-level) In relatively concentration (1.0 M), Faradaic (FE) reaches 82.2% under 1.0 A·cm−2 environment (pH=1.8). Particularly, when as 1.5 A·cm−2, FE still keeps 75.8%. Experimental theoretical studies reveal that presence PIL on catalyst can well inhibit H+ diffusion surface, enrich more facilitate C-C coupling reaction. Acidic reduction promising way utilization, which selectivity activity need improvement. Here, authors report boost ampere level density.
