Developing and fabricating cost‐effective materials for efficient thermocatalytic reduction of CO2 to CO under mild conditions is a promising and practical way to sustainable and green low‐carbon energy systems, which remains a challenge. Herein, a facile high‐temperature pyrolysis strategy for the synthesis of efficient ultrathin nitrogen‐modified...
