Rhodium, with the chemical symbol Rh, was discovered in 1803 by the English chemist William Hyde Wollaston. As a member of the platinum group, Rhodium is a noble metal often mined in conjunction with platinum and palladium. It is relatively rare on Earth, with an average abundance of about 0.001 ppm in the Earth's crust.

The applications of Rhodium are diverse, ranging from jewelry making to technological and industrial uses. It is renowned for its ability to be extremely heat-resistant and corrosion-resistant. Rhodium is commonly used in catalyst production, particularly in vehicle catalytic converters. Furthermore, it is employed in the electronics industry, optics, and medicine.

Future applications could focus on air purification technologies and renewable energies. Researchers are exploring the use of Rhodium in advanced catalysts for fuel cells as well as applications in hydrogen production.
