There are many substances that can "poison" platinum catalysts, causing their catalytic activity to decrease or even lose activity. For example, organic compounds containing elements such as nitrogen, phosphorus, and sulfur, and ionic compounds containing heavy metals such as tin, lead, mercury, bismuth, and arsenic. Therefore, it is necessary to pay special attention to the use of platinum catalysts to prevent platinum catalysts from contacting these poisonous substances. There are many types and forms of platinum catalysts. Therefore, in the application process, a suitable platinum catalyst must be selected according to the characteristics of the reaction system to achieve the best
