| Application: | Iridium(IV) chloride hydrate can be used: • To fabricate an Ir-decorated graphene electrode for vanadium redox flow batteries. • As a precursor to synthesize iridium oxide nanoparticles. These nanoparticles can act as a stable catalyst for the hydrogenation of a series of nitrogen heterocycles. • To prepare Ir single atom catalyst (Ir1–Ni(OH)2) for oxygen evolution reaction. |
| General description: | Iridium(IV) chloride hydrate is a black crystallinesolid used as a precursor to synthesize Ir-based catalysts and nanoparticles. |
