New progress in microenvironment regulation of carbon dioxide electrocatalytic interface under acidic conditions

Recently, Professor Li Chunzhong and Jiang Hongliang Distinguished Researcher from the School of Chemical Engineering of East China University of Science and Technology have made new progress in the study of carbon dioxide electrocatalytic interface microenvironment regulation under acidic conditions

The CO₂ electrocatalytic reaction usually occurs in alkaline/neutral flow cells with severe carbonate formation

This work modulates the electrocatalytic interface microenvironment by introducing hydrophobic polytetrafluoroethylene (PTFE) into the catalytic layer of the gas diffusion electrode.

The figure shows the regulation mechanism of gas-liquid-solid three-phase interface hydrophilicity and hydrophobicity on gas mass transfer

For the electrocatalytic reduction process involving CO 2 gas, this work innovatively uses PTFE to control the hydrophilicity and hydrophobicity of the catalytic layer.

The first author of the above related work is Sheng Xuedi, a postgraduate student of East China University of Science and Technology, and the corresponding authors are Professor Li Chunzhong and Jiang Hongliang Distinguished Researcher
