Metal-free C2N catalyst with superior H2O/SO2 tolerance for NO reduction with CO during incomplete combustion process

NO and CO, as common pollutants in coal-fired power plants, can be directly reduced to N2 and CO2 molecules during the incomplete combustion process on a double atomic catalyst (DAC, Si-dimer doped C2N monolayer) without any reversible possibility at room temperature and/or practical temperature (600 K).
