The catalysts with an ionomer “shell” facilitate the mass transport for electroreduction of carbon dioxide.

Caption

The ionomer is homogeneously distributed around each catalyst particle. The GDE using the ionomer-confined electrocatalyst optimizes the distribution of ionomer within catalyst layer, which not only builds paths for the promoted transport of ions but also facilitates the mass transfer of CO2.
