The primary key application was electroplating for attractive makes use of and as corrosion-resistant coating.[20] The introduction with the 3-way catalytic converter by Volvo in 1976 enhanced the need for rhodium.
Rhodium catalysts may also be used in C-C bond-forming reactions like Suzuki or Heck coupling. These are very important artificial routes for generating complicated organic molecules, especially in pharmaceutical and agrochemical industries.
Rhodium can be used as catalysts inside the chemical business, for building nitric acid, acetic acid and hydrogenation reactions.
Organic position Rhodium has no acknowledged Organic function. It is a suspected carcinogen. Natural abundance Rhodium is definitely the rarest of all non-radioactive metals.

(Tennant investigated this residue and from it he ultimately isolated osmium and iridium.) Wollaston concentrated on the solution of dissolved platinum which also contained palladium. He removed these metals by precipitation and was remaining with a good looking purple Remedy from which he obtained rose purple crystals. These have been sodium rhodium chloride, Na3RhCl6. From them he finally manufactured a sample with the metal alone. Glossary
