What are the types of precious metal catalysts?

Posted by sarvesh velankar on July 15th, 2021

Precious metals such as gold, palladium, platinum, and silver help catalyse chemical reactions, owing to their activity, selectivity, and recyclability. They are also valuable for multiple industries, including pharmaceuticals, agrochemicals, flavours and fragrances, fine and bulk chemicals. Based on the type, platinum has significant growth during the forecast period.

A precious metal catalyst consists of highly dispersed precious metal particles supported on a high surface area. They are noble metals widely used in the chemical industry owing to their ability to speed up the chemical process. Each has unique characteristics primarily used for laboratory experiments.

Heterogeneous catalysts

These are useful in chemical industries because of their activity, selectivity, and recycle capacity. Industrial catalyst processes are highly cost-effective as they involve moderate reaction conditions, high yields, high throughputs, and minimal byproduct and process costs.

The application of precious metal chemicals is in liquid phase hydrogenation, dehydrogenation, and oxidation reactions. It requires finely divided material easily suspended within the reaction medium. The metal location, size, and oxidation state influence a catalyst’s selectivity. The support also facilitates improved metal recovery.

Advantages

The advantages include strong technical assistance, capacity enhancement in short duration, higher metal return, shorter delivery time and world-class production facilities. The types of heterogeneous catalysts are platinum, palladium, rhodium, and ruthenium.

Homogeneous catalysts

They are precious metal compounds or salts associated with organic ligands. They are great for chemical reactions based on recyclability.A homogeneous catalyst and reactant are in the same phase during the entire reaction time, thus eliminating pore diffusion limitation on an industrial scale.

Advantages

As the homogeneous catalyst mechanism is better understood, manipulation of process parameters becomes easier. Platinum group metal homogeneous catalysts are essential in homogeneous catalyst reactions. The types include platinum, palladium, rhodium, ruthenium, iridium, gold, and silver.

Salts and solutions

Manufacturer of precious metal catalyst also supplies inorganic salts and solutions used in diverse applications, including automobiles, pharmaceuticals, fine chemicals, cancer treatment materials, jewel and electronic product plating, mirrors, and voting ink. They customise products according to the client’s needs with technical expertise to improve processes. The types include platinum, palladium, rhodium, and ruthenium.

Suitable supports

For powder precious metal catalysts, the support plays an active role in determining metal loading and dispersion. The metal location, size, and oxidation state influence a catalyst’s selectivity.

There is no doubt that catalysis has played a significant role in the global chemical industry over the past few decades. Pharmaceutical manufacturers employ various platinum group metal catalysts to facilitate the production of regulatory starting materials while changing with modern development.

How to choose the supplier?

When choosing the precious metal catalyst supplier, ensure they are ISO and NABL certified. They represent the company’s capabilities, the robustness of processes and strengthens the commitment to serve customers globally. Companies employing quality management systems and proficient testing of precious metals are ideal and trustworthy.
