Methane is one of the important pollutants of natural gas automobile and industrial source exhaust emission, and is a greenhouse gas with a high greenhouse effect coefficient, so how to control and eliminate methane emission is one of the hot spots of research in the environmental field. The catalytic combustion technology is one of the most effective methods for effectively controlling methane emission, the catalytic combustion method has the advantages of high purification efficiency, wide concentration of treated waste gas, no secondary pollution and the like, and the core of the method is to design and prepare a high-performance catalyst.
In the catalytic combustion technology of methane, the most commonly used is a supported noble metal palladium-based catalyst. In order to solve the problem of insufficient thermal stability of the single palladium catalyst and reduce the cost, the utilization of precious metal and non-precious metal to form bimetallic materials has become a hot point of research in recent years. Satsuma et al (Catalysis Today 242 (2015) 308-314) found that the introduction of cobalt was beneficial for increasing the combustion reactivity of palladium-based catalysts towards methane. Tang et al found that encapsulation of palladium cobalt in a ZSM-5 molecular sieve improved the methane combustion activity and stability of the catalyst (Chemical Engineering Journal 418 (2021) 129398). In addition, the introduction of cerium can greatly improve the methane combustion activity and thermal stability of the noble metal catalyst (Journal of Environmental Sciences 24 (2012) 507-511).
