Preparation of K Modified Three-Dimensionally Ordered Macroporous MnCeO<sub>x</sub>/Ti<sub>0.7</sub>Si<sub>0.3</sub>O<sub>2</sub> Catalysts and Their Catalytic Performance for Soot Combustion

Soot particles in diesel engine exhaust is one of the main reasons for hazy weather and elimination of them is urgent for environmental protection. At present, it is still a challenge to develop new catalysts with high efficiency and low cost. In this paper, a kind of K modified three-dimensionally...
