Nanobubble-infused electrolytes for enhanced mass transfer in liquid-fed CO2 electroreduction

Year: 2025

Type: article

Abstract: The limited solubility and slow diffusion of CO2 in aqueous electrolytes represent a challenge for electrochemical CO2 conversion in aqueous systems, imposing significant mass transfer barriers, particularly at high current densities. Here, the authors introduce a nanobubble-infused electrolyte strategy that leverages the unique properties of nanobubbles, including localized CO2 enrichment, enhanced diffusion, and micro-convection to achieve a 10-fold increase in the volumetric mass transfer coefficient and a 42.3% improvement in the limiting current density.
