Catalysts play a vital role in the field of chemistry by accelerating chemical changes without participating in the final product of the reaction. Among them, platinum (PT), as an efficient and stable precious metal catalyst, is widely used in various chemical changes. This paper will discuss the reaction principle of platinum catalyst and its application in different fields in detail.
First, let's understand the reaction principle of platinum catalyst. Platinum catalyst mainly plays a role in reducing the activation energy of the reaction in the chemical reaction. The activation energy is the lowest energy state required to form a molecule to achieve a reaction. By providing a surface suitable for the formation of molecular adsorption and reaction, platinum catalysts make it easier for the formation of molecules to reach an active state, thereby accelerating the reaction rate.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48710.html
Next, let's take a look at where platinum catalysts are widely used.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48710.html
Platinum catalyst is widely used in automobile exhaust treatment system. By catalyzing recovery and oxidation reactions, platinum catalysts can convert harmful components in exhaust gases, such as carbon monoxide (CO), nitrogen oxides (HC) and nitrogen oxides (NOx), into harmless carbon dioxide (CO2), water (H2O) N2 (N2). According to the research, the use of platinum catalyst for automobile exhaust treatment system can reduce the consumption of harmful substances in exhaust gas to a few percent of the original, greatly improving air quality.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48710.html
Platinum catalysts also play an important role in the petrochemical field. For example, in the petroleum cracking process, platinum catalysts can promote the cracking of heavy hydrocarbon molecules to produce light hydrocarbons such as gasoline and diesel. In addition, platinum catalysts can also be used to catalyze the reorganization process to convert low-octane naphtha into high-octane gasoline and improve the quality of gasoline.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48710.html
Platinum catalysts are also widely used in the field of fuel cells. A fuel cell is a device that converts chemical energy directly into electrical energy, in which the platinum catalyst acts as the electrode catalyst, which can promote the oxidation reaction of the anode hydrogen gas and the negative electrode oxidation reaction, and then generate an electric current. Due to the excellent catalytic activity and stability of platinum catalyst, fuel cells have high energy conversion efficiency and long service life.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48710.html
It is worth noting that although platinum catalysts are widely used in many fields, their relatively high price limits their large-scale application in some fields. Therefore, the research and development of new, efficient and low-cost catalyst substitutes is an important research content in the field of chemistry.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48710.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48710.html
