“…As a metal, it is unworkable but finds use in space components and specialty spark plugs when alloyed with Pt. In recent years, nanoparticles of Ir have been synthesized using various chemical techniques [38,39] and tested as catalysts [40][41][42] and as sensors [43][44][45]. Examples of catalytic activity are the use of Ir NPs for the degradation of dyes [38] and for hydrogenation reactions [41,42].…”

Iridium is very important element among the all transition metals with highest reported oxidation state i.e. +9 in gas phase existing species IrO4+. Instead of its less reactivity, it forms number of compounds having oxidation states between -3 to +9. It is second known densest element after osmium. Till now its toxicity and environmental impact is not much more reported and thus it may be use as green element in various fields of its application. Reason behinds it’s less toxicity and environmental impact may be due to its less reactivity and solubility. Corrosion and heat resistant properties of Iridium makes it much more useful element for alloying purpose. Iridium is the member of platinum family and used as catalyst due to its variable oxidation states. Iridium(III) complexes show great catalytic activity in both the acidic and basic medium for various organic as well as inorganic chemical transformations. Catalyst may be defined as the substance which can increases the rate of reaction of a specific chemical reaction without changing its own composition. Iridium is only one reported catalyst which is able to capture the sunlight and convert it into the chemical energy. Thus, it may be used in artificial photosynthesis process to solve our future food problem. Instead of these advantage, Iridium chemistry and its catalytic activity is not much reviewed till date, therefore, present review includes a brief introduction about chemistry and catalytic application of Iridium, which proof itself a boon for beginners to start their research career in the field of Iridium chemistry.

“…[15][16][17][18][19][20][21][22] Especially, their possession of highly reactive surfaces, which arise from the high surface to volume ratio along with a low number of atomic neighbors, brands nanoparticles as a practical candidate for many scientific efforts especially in the area of catalysis. [23] Presently, research endeavors on nanoparticle synthesis have been focused on dimensionally controllable synthetic methods, [24][25][26] optimal application approaches, [27] and the development of efficient large scale manufacturing. [28] The development of nanoparticles, which have been defined restrictively to sizes ranging from 1 nm to no larger than 100 nm, have even made once inert or less reactive bulk materials into highly efficient catalytic systems.…”

This Minireview summarizes a variety of intriguing catalytic studies accomplished by employing unsupported, either solubilized or freely mobilized, and small organic ligand-capped palladium nanoparticles as catalysts. Small organic ligands are gaining more attention as nanoparticle stabilizers and alternates to larger organic supports, such as polymers and dendrimers, owing to their tremendous potential for a well-defined system with spatial control in surrounding environments of reactive surfaces. The nanoparticle catalysts are grouped depending on the type of surface stabilizers with reactive head groups, which include thiolate, phosphine, amine, and alkyl azide. Applications for the reactions such as hydrogenation, alkene isomerization, oxidation, and carbon-carbon cross coupling reactions are extensively discussed. The systems defined as “ligandless” Pd nanoparticle catalysts and solvent (e.g. ionic liquid)-stabilized Pd nanoparticle catalysts are not discussed in this review.
