Abstract Electrode‐electrolyte interfacial modification by hydrophobic molecules represents a promising strategy for suppressing competing proton reduction in acidic electrocatalytic carbon dioxide reactions (CO 2 RR), meanwhile sacrificing extra overpotential due to increased ohmic resistance. Herein, multifunctional conductive polymer, polyaniline modified p‐aminobenzenesulfonic acid (ABSA‐polyaniline), is constructed between Cu catalyst layer and electrolyte simultaneously create an ideal microenvironment CO RR enhance the charge transfer ion transport processes at electrochemical reaction interface. This polymer balances local hydrophobicity, promotes adsorption activation, regulates mass of K + , H OH − ions, thus significantly enhancing kinetics medium, yielding high Faraday efficiency (FE = 81%) multicarbon products 600 mA cm −2 . More importantly, compared with commonly used molecules, nature ABSA‐PANI helps reduce resistance electrode, leading notably lowered cathode industrial‐grade current density improve energy over wide potential window. work sheds light on development highly efficient systems, especially those low alkali cation concentrations concentrations.

Amid global efforts toward carbon neutrality, nanoconfined catalysis has emerged as a transformative strategy to address energy transition challenges through precise regulation of catalytic microenvironments. This review systematically examines recent advancements in systems for carbon-based conversion (CO2, CH4, etc.), highlighting their unique capability modulate electronic structures and reaction pathways via quantum confinement interfacial effects. By categorizing architectures into dimension-oriented frameworks (1D nanotube channels, 2D layered interfaces, 3D core-shell structures, heterointerfaces), we reveal how geometric constraints synergize with mass/electron transfer dynamics enhance selectivity stability. Critical optimization strategies—including heteroatom doping optimize active site coordination, defect engineering lower barriers, surface modification tailor local microenvironments—are analyzed elucidate roles stabilizing metastable intermediates suppressing catalyst deactivation. We further emphasize the integration machine learning, situ characterization, modular design essential establish structure–activity correlations accelerate industrial implementation. work provides multidimensional perspective bridging fundamental mechanisms practical applications advance carbon-neutral systems.
