A Review on Osmium: Beneficiation Opportunities

Abstract

This review summarises the safe production of osmium and its compounds and its functionality from both the chemistry and materials perspectives. Osmium (Os) is one of the platinum group metals. A review of the available data shows that there is a lot of potential for osmium (II) compounds to be used for traffic signalling as molecular signal gates using electrochemical generated power. Osmium (II) compounds can also be used for biomedical applications on the development of anti-cancer drugs. Organic compounds of osmium have also been found to possess excellent electrochemical properties which are useful for redox flow battery. This review of osmium and its compounds possess a variety of correlated properties with a potential to put an emergent demand on osmium for various applications. The results proved that Os complexes have excellent electrochemical properties and has rendered Os complexes as “smart complexes”.
