A stable and selective electrocatalyst for CO 2 reduction was fabricated by covalently attaching graphitic carbon nitride onto multiwall carbon nanotubes (g‐C 3 N 4 /MWCNTs). The as‐prepared composite is able to reduce CO 2 exclusively to CO with a maximum Faraday efficiency of 60 %, and no decay in the catalytic activity was observed even after 50 h of reaction. The enhanced catalytic activity towards CO 2 reduction is attributed to the formation of active carbon–nitrogen bonds, high specific surface area, and improved material conductivity of the g‐C 3 N 4 /MWCNT composite.
