Abstract:

This paper analyzed the application of PGMs in the automobile exhaust purification catalysts through the supply and demand data.Then,it explores its major R & D Status from literature and patents especially focus on the last five years of research and discovery.Meanwhile,analysis of how to reduce the use of platinum group metals technology and how to improve catalytic performance technology.In addition,it also related to the carrier,a honeycomb structure,the trap,the cerium-zirconium functions,diesel exhaust gas purification,exhaust catalyst recovery,and to the other aspects of the biosphere.The application of PGMs in the automobile exhaust purification catalysts tends to efficiently utilize PGMs and keep cost down as possible.To achieve these goals,it uses lower-cost Palladium instead of costly Platinum,and intensifies the performance of PGMs.Transition metal oxides and catalyst auxiliaries play an increasingly important role in the utilization of PGMs.So this article carried out an in-depth study on the usage amount,distribution in catalyst,adsorptive property of PGMs,etc.In the future, the catalytic activity of other metals (such as transition metal oxides) will be improved as possible,and the dosage of Platinum in the automobile exhaust purification catalysts will be continually decreased.Therefore,it will seek out the best balance point of the cost and efficiency.
