Rhodium and Rhodium-Alloy Films and Nanoparticles

Noble metals are key to various research fields and Noble metal nanomaterials are directly relevant to optics, catalysis, medicine, sensing and many other applications. Rhodium-based nanomaterials have been less studied than metals such as gold, silver or platinum. There have been leaps and bounds in characterization tools over the years, and knowledge about rhodium chemistry and nanomaterials are expected to grow. With high expectations driving the use of rhodium nanoparticles as catalysts for automotive exhaust gas, catalysts for hydrogen and oxygen precipitation reactions in electrolytic cells, the established applications of rhodium materials in fields such as electronics and appliances, anti-cancer drugs and aerospace are being revisited. This review covers different strategies for the synthesis of rhodium films and nanoparticles and provides a broad overview of the reported applications.
