With the strengthening of peoples environmental awareness as well as the stringent of countries environmental legislation, governance requirements for motor vehicle exhaust are increasingly high.Not only can catalytic combustion make fuel to achieve complete combustion at a lower temperature, but also have some advantages simple equipments, low energy consumption, high removal rate and less formation of NOx secondary pollution, for optimizing the energy structure in China, reducing greenhouse gas emissions and reducing atmospheric pollution is of great significance.The traditional catalyst in the presence of a high pressure drop, high energy consumption shortcomings, has been unable to meet high quality requirements ,so there is an urgent need to develop a new catalyst, at the same time having high activity at low temperature and thermal stability, but also having high mechanical strength and thermal shock resistance.
