Abstract
Abstract In this work, a scalable one‐step glucose blowing method has been used to prepare a porous N‐doped carbon supported Cu nanoparticles (Cu‐NC) composite catalyst for CO 2 electroreduction. This Cu‐NC catalyst demonstrates efficient catalytic activity for CO 2 ‐to‐C1 product (CO and formate) conversion, with a high efficiency of 69 % at an overpotential of 590 mV. The excellent catalytic activity is correlated to the structure of this composite and the N‐species (pyridinic and graphitic nitrogen) in the carbonaceous matrix that may promote the CO 2 adsorption and subsequent formation of reduction reaction intermediates and products.
