We demonstrate a general and efficient self‐templating strategy towards transition metal–nitrogen containing mesoporous carbon/graphene nanosheets with a unique two‐dimensional (2D) morphology and tunable mesoscale porosity. Owing to the well‐defined 2D morphology, nanometer‐scale thickness, high specific surface area, and the simultaneous doping of the metal–nitrogen compounds, the as‐prepared catalysts exhibits excellent electrocatalytic activity and stability towards the oxygen reduction reaction (ORR) in both alkaline and acidic media. More importantly, such a self‐templating approach towards two‐dimensional porous carbon hybrids with diverse metal–nitrogen doping opens up new avenues to mesoporous heteroatom‐doped carbon materials as electrochemical catalysts for oxygen reduction and hydrogen evolution, with promising applications in fuel cell and battery technologies.
