Effect of Dispersing Solvents for an Ionomer on the Performance of Copper Catalyst Layers for CO₂ Electrolysis to Multicarbon Products

To explore the effects of solvent-ionomer interactions in catalyst inks on the structure and performance of Cu catalyst layers (CLs) for CO₂ electrolysis, we used a “like for like” rationale to select acetone and methanol as dispersion solvents with a distinct affinity for the ionomer backbone or sulfonated ionic heads,...

In operando-formed interface between silver and perovskite oxide for efficient electroreduction of carbon dioxide to carbon monoxide

Electrochemical carbon dioxide (CO₂) reduction (ECR) is a promising technology to produce valuable fuels and feedstocks from CO₂. Despite large efforts to develop ECR catalysts, the investigation of the catalytic performance and electrochemical behavior of complex metal oxides, especially perovskite oxides, is rarely...
