“…Iridium nanochain-like structures were prepared using sodium borohydride as a reducing agent and ascorbic acid (AA, which is biocompatible) as a capping agent in aqueous medium. 26 In a typical synthesis, an aqueous IrCl 3 solution (1 mM) was stirred in the presence of 2 mM ascorbic acid followed by the addition of freshly prepared sodium borohydride solution (20 mg in 10 mL water) and the mixture was heated at 80 1C in air under magnetic stirring for 6 hours and cooled down to room temperature. During the reaction, the colour of the solution changed from light pale yellow to light brown.…”

Iridium nanostructures with different morphologies are synthesized by a simple, environmentally friendly approach in aqueous media under mild conditions. The morphology dependent electrocatalytic activity of Ir nanochains and nanoparticles towards oxygen reduction reaction (ORR) has been demonstrated in both acidic and alkaline media. Comparative electrochemical studies reveal that nanochains exhibit significantly enhanced ORR activities in both acidic and alkaline media as compared with nanoparticles, as a result of the continuous structure of interconnected particles. The mechanism of oxygen reduction on Ir nanostructures predominantly follows a four-electron pathway in alkaline and acidic solutions. Excellent stability and good selectivity towards methanol tolerance are reported.

Spontaneous formation of ruthenium nanochains is accomplished in aqueous medium under mild conditions using a seed mediated protocol with cetyl trimethylammonium bromide (CTAB) as the capping agent. They are formed due to the random self-assembly of Ru seeds of ∼3.5 nm size. These 1D nanostructures exhibit better catalytic activity towards the oxidation of CO relative to the ∼3.5 nm seeds and 6 nm Ru nanospheres. The synthesis strategy adopted here is found to be simple, facile and environmentally friendly.

“…The chemical characteristics of Iridium nanoparticles is mainly based on composition, and surface morphology. It was identified that, the surface enhanced Raman scattering was studied well for Iridium nanochains than Iridium nanoparticles [23][24]. Nanomaterials based on transition metals and noble metals show versatile chemical properties.…”

Nanoscience is assumed to have capability to change the efficiency of the current electronic and electrical devices. So nanotechnology is being developed to achieve the same. Various kinds of nanomaterials are being prepared such that they show tremendous properties at the nanoscale dimensions. Hence, it is worth studying about the synthesis of nanomaterials. The information that we present in this paper corresponds to a basic review on the synthesis and recent work done on nanomaterials. The distinctness of this review is that, the classification and major types of nanomaterials has been reported. The literature was collected through internet, from various available sources. The synthesis methods that have been discussed are sputtering, hydrothermal, microwave assisted, and electrochemical and chemical reduction methods.
