1875, German E. Jacobs established the first contact device for producing fuming sulfuric acid in Creutzner, and produced the required platinum catalyst, which was the pioneer of solid industrial catalyst. Platinum is the first industrial catalyst, and it is still the catalytic active component of many important industrial catalysts.

/kloc-in the 0/9th century, there were few kinds of products in the catalyst industry, all of which were produced by manual workshops. Because of the important role of catalyst in chemical production, the manufacturing method of industrial catalyst has been regarded as a secret since it came out.

Platinum catalyst:

It is mainly used for ammonia oxidation, petroleum hydrocarbon reforming, oxidation and hydrogenation of unsaturated compounds, and removal of carbon monoxide and nitrogen oxides from gas. It is a catalyst, which is often used in chemistry, petroleum and chemical reactions. It has the advantages of high catalytic activity, strong selectivity, convenient preparation of catalyst and low dosage, and can be compounded with other metals or active components of cocatalyst by changing and improving the manufacturing method to optimize the catalytic performance.
