General description

Iridium(IV) chloride hydrate is a black crystallinesolid used as a precursor to synthesize Ir-based catalysts and nanoparticles.

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.
