Application prospect of platinum group metal nanoparticles in automobile exhaust gas purification catalyst

Vehicle exhaust pollution control is mainly achieved by improving oil quality, engine performance, combustion efficiency, and installing exhaust purifiers. Platinum group metals are mainly platinum, palladium and rhodium, the three kinds of noble metal nanoparticles can be used in automobile exhaust purification catalysts. Rhodium prices are currently very high, so there is more demand for platinum and palladium nanoparticles. We are also seeing widespread automotive and industrial use of catalytic converters using platinum and palladium.

Due to their high melting point and strong corrosion resistance, pt platinum nanoparticles are important materials for catalysts in the automotive industry. In addition, driven by the heavy vehicle market in China, platinum demand in the automotive industry is expected to continue to increase by the end of this year.

In industrial use, platinum is currently gaining share in the auto-catalyst market as it continues to replace outperforming palladium on a one-to-one basis in gasoline-engine vehicles. The bulk of nano platinum consumption this year will come from the automotive industry and other industrial uses.

In addition to industrial demand, the development of the hydrogen energy industry also drives the demand for nano platinum. As a large part of renewable energy, hydrogen energy is the key to the deep decarbonization of the global industrial sector, so the entire hydrogen fuel industry has also been boosted. Among them, platinum is an indispensable material in the current hydrogen energy stack technology, and the long-term demand is expected to increase significantly.

Platinum group metals are used as catalysts for automobile exhaust gas purifiers and catalysts for fuel cells. Therefore, on the demand side, with the recovery of the production and sales levels of the automobile industry in the third quarter, the tightening of China 6 emission regulations, and the promotion of the hydrogen economy, the price and demand for platinum group metals will be well supported. This makes it possible to catalyze many difficult-to-achieve reaction processes by platinum catalysts, and enables many industrial production processes such as petroleum and chemical industry to be improved and optimized due to the use of newly developed platinum catalysts, simplifying the process and increasing economic benefits. Platinum catalysts still have great prospects for development.
