Rhodium(III) chloride refers to inorganic compounds with the formula RhCl3(H2O)n, where n varies from 0 to 3. These are diamagnetic solids featuring octahedral Rh(III) centres. Depending on the value of n, the material is either a dense brown solid or a soluble reddish salt.
Rhodium chloride is prepared from rhodium metal powder by: adding rhodium powder and hydrochloric acid into U-shaped electrolytic tank, providing AC current onto two electrodes to dissolve in solution and obtaining aqueous solution of rhodium hydrochloride, filtering the solution of rhodium hydrochloride, distilling to ...
Application. Rhodium(III) chloride precursor may be used to dope graphene with Rh nanoparticles to prepare hybrids for electrocatalysis in energy, sensing and biomedical sectors.
Rhodium is a relatively inactive metal. It is not attacked by strong acids. When heated in air, it combines slowly with oxygen. It also reacts with chlorine or bromine when very hot.
