Why is platinum used as catalyst and the application of platinum catalyst

Platinum, platinum (Pt) in the periodic table of chemical elements, occupies an irreplaceable position in the field of catalysts due to its unique physicochemical properties. This article will analyze in detail the reasons why platinum is widely used as a catalyst, and explore the application of platinum in various industries.

The reason why platinum is used as a catalyst first benefits from the characteristics of high adsorption capacity on the surface. The surface of platinum can adsorb oxygen, hydrogen and other molecules, and these adsorbed molecules can interact with the surface atoms of platinum through electron transfer, resulting in a series of chemical changes. For example, after adsorption of oxygen molecules, oxides can form with platinum atoms on the surface of platinum, while hydrogen molecules can form hydrogen atoms on the surface of platinum. This adsorption provides the initial activation energy for the chemical change, thereby lowering the energy threshold required for the reaction.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48729.html

There are also a large number of active sites on the surface of platinum, which can further catalyze the reaction. When oxygen molecules occupy these active sites, it can not only accelerate the activity of oxygen atoms, but also catalyze oxidation, hydrogenation, dehydrogenation, and recovery. This catalytic reaction makes platinum catalyst play an important role in petrochemical, pharmaceutical production and other fields.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48729.html

In addition, platinum catalysts have the ability to combine. It can not only adsorb a single molecule, but also adsorb multiple molecules to form a complex. The formation of this complex generally requires a certain temperature and reaction conditions, but the formation of the complex can significantly improve the efficiency and speed of chemical changes, making the reaction more efficient and controllable.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48729.html

Platinum catalysts are widely used. In the petrochemical industry, platinum catalyst is used to prepare fuel, fertilizer and other important chemical raw materials; In the pharmaceutical field, platinum catalysts are used to generate various drug intermediates to help the pharmaceutical industry improve production efficiency; In the field of environmental protection, platinum catalysts are important tools for purifying air and treating wastewater, and play a vital role in environmental protection.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48729.html

In terms of specific value, about 50% of the world's annual platinum production is used in triple-effect converters for automotive exhaust purification systems, which is enough to prove the importance of platinum catalysts in the field of environmental protection. However, platinum catalyst also plays an irreplaceable role in fuel cell electrode catalyst, petrochemical catalytic recombination selective hydrogenation and so on.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48729.html

In summary, platinum has become a highly efficient catalyst due to its unique physical and chemical properties, especially its high adsorption capacity, surface active sites and combined effects. Platinum catalyst has broad application prospect and irreplaceable role in petrochemical, pharmaceutical and environmental protection fields. In the future, with the continuous development of science and technology and the continuous expansion of application fields, platinum catalysts will make greater contributions to the development of human society.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48729.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48729.html
