Conventional alkaline and neutral CO2-to-CH4 systems suffer carbon loss, and recovering the lost carbon requires input energy exceeding the heating value of CH4. Here, the authors report a chelating strategy to obtain Cu-N/O single sites decorated Cu clusters, which enables energy- and carbon-efficient CH4 electroproduction in an acidic system.
