| Abstract: | Reduction of NO to N2O or N2 was studied over activated carbons using thermal desorption technique. The addition of other metals such as Zn, Cu, Fe, Ni, Sn, Mn or Ce, to potassium doped carbon remarkably enhanced direct NO reduction or NO reduction by carbon. The high activity might be ascribed to the synergism between potassium-metal on the carbon surface. |
