Abstract The present article defines the state-of-the-art of iridium nano catalyst. In this article, the attempts are made to discuss the syntheses, characterizations, applications, toxicity and future perspectives aspects. Over all, the available information on nano iridium catalyst is included in this article. The most important applications of nano iridium catalyst are water splitting, hydrogen and oxygen generation, chemical reactions, fuel cells, sensors (detection), absorption and some other miscellaneous. The growth of the research papers and applications of iridium nano catalyst indicated bright future in various industrial applications. It was observed that iridium nano catalysts are not fully developed and under their development stages. Certainly, these nano materials will be very valuable in a wide range of scientific and industrial applications in near future.
