Accelerate Mass Transport of Proton and Carbon Sources by Super-Hygroscopic and Porous Nanosheets for Continuous CO₂-To-Ethylene Upgrade.

ABSTRACT: Gas-water/catalyst triple-phase interface and the microenvironment play critical roles in the reaction kinetics and production rate of electrochemical carbon dioxide reduction reactions (CO₂RR), which steer concerted proton-electron transfer steps. Inspired by Tillandsia leaves, which efficiently capture H₂O and CO₂ from the air, copper nanosheets with dual-functional channels are we designed: the superhygroscopic network enables capillary condensation, converting H₂O(g) into H₂O(l) to form H₂O channels that ensure a stable supply of protons, while the CO₂ channels formed by the microporous structure enhance the diffusion of CO₂, thus enriching the carbon source. This synergistic design creates an optim
