| Abstract: | A series of complex oxide La1-xNaxCo0.5Mn0.5O3 catalysts,in which La3+ is partly substituted for Na+,were synthesized at low temperature through a combustion process.The catalytic activity of the catalysts for simultaneous removal of NOx and diesel soot particulates were examined in details using temperature programmed reaction(TPR) technique. |
