Potassium-doped sodalite: A tectoaluminosilicate for the catalytic material towards continuous combustion of carbonaceous matters
چکیده انگلیسی

A novel approach has been proposed for stabilization of potassium in combustion of carbonaceous soot matters emitted from diesel engine vehicles. Sodalite, a clathrate aluminosilicate zeolite, is employed as a support for holding catalytically active potassium species. This approach resulted in a high-catalytic activity and the activity is further enhanced after hydrothermal treatment at 800 °C. Such kinds of tectoaluminosilicate hold potassium strongly and possess high stability against high temperatures and alkaline conditions induced by hydrated potassium ions under practical driving conditions.
