Application

Iridium(III) chloride hydrate can be used:
  • As a precursor to synthesize IrO2 nanofibrous catalyst for oxygen evolution reaction.
  • As a starting material to prepare Ir complex that acts as an additive to hole transport layer in perovskite solar cells. This Ir complex helps to reduce recombination rate and enhances the stability of solar cells.
  • To fabricate thin and highly active IrO2 anodes for proton exchange membrane electrolyzer cells (PEMECs).
  • As a precursor to synthesize ionic Ir metal complexes for efficient flexible green light-emitting electrochemical cells. This leads to enhanced quantum efficiency and luminescence.

General description

Iridium(III) chloride hydrate is a dark green to black hygroscopic solid that is widely used as a Ir source/precursor to synthesize Ir nanoparticle and battery materials.
