Precious metal catalyst<\/h2><\/div>\n\n\n\n

A precious metal catalyst is a type of precious metal material that can alter the rate of a chemical reaction without itself participating in the final product of the reaction. Almost all precious metals can be used as catalysts, but the commonly used ones are platinum, palladium, rhodium, silver, ruthenium, etc. Among them, platinum and rhodium are particularly widely used. Their d-electron orbitals are not fully filled, and the surface is prone to adsorb reactants with moderate strength, which is conducive to the formation of intermediate “active compounds” and has high catalytic activity. At the same time, they also have comprehensive excellent characteristics such as high temperature resistance, oxidation resistance, and corrosion resistance, making them the most important catalyst materials.<\/p>\n\n\n\n

Product Introduction<\/h2><\/div>\n\n\n\n

In 1831, Phillips proposed the contact method using platinum as a catalyst to produce sulfuric acid. By 1875, this method had been industrialized, marking the earliest industrial application of precious metal catalysts. Subsequently, the industrial application of precious metal catalysts has emerged one after another. In 1913, platinum mesh catalyst was used for ammonia oxidation to produce nitric acid; In 1937, Ag\/Al2O3 catalyst was used for the oxidation of ethylene to produce ethylene oxide; In 1949, Pt\/Al2O3 catalyst was used for petroleum reforming to produce high-quality gasoline; In 1959, PdCl2 CuCl2 catalyst was used for the oxidation of ethylene to acetaldehyde; By the late 1960s, rhodium complex catalysts for the low-pressure carbonylation of methanol to acetic acid had emerged. Since 1974, precious metal catalysts (mainly platinum, supplemented by palladium and rhodium) have been widely promoted and applied in automobile exhaust purification, and quickly developed into the most widely used precious metal catalysts. The development and application of precious metal catalysts have been thriving for over a hundred years (1875-1994). New varieties, new preparation methods, and new application fields are constantly emerging, and the relevant basic theories are also constantly being improved. With the continuous advancement of science and technology, precious metal catalysts will continue to play an important role in some new fields. Of course, due to the scarcity and high cost of precious metal resources, people are constantly researching and developing non precious metal or low content precious metal catalysts.<\/p>\n<\/div><\/div>\n\n\n\n
