Claim 0:
1. A method for making iridium oxide nanoparticles, comprising steps of:
a) dissolving an iridium salt in a salt-dissolving solvent to obtain a salt-containing solution;
b) after step a), mixing a complexing agent with the salt-containing solution to obtain a blend solution, the complexing agent including a complexing compound for complexing iridium ions of the iridium salt, and which has a molar amount larger than that of the iridium salt; and
c) after step b), adding an oxidating agent to the blend solution to permit oxidation of the iridium ions and obtain a product mixture, the oxidating agent including an oxidant compound,
wherein a molar ratio of the complexing compound to the iridium salt is controlled in a predetermined range to permit the product mixture produced in step c) to include iridium oxide nanoparticles,
wherein the salt-dissolving solvent in step a) is water, and
wherein between steps b) and c), the method further comprises a step of b′) adding a stabilizing agent to stabilize the iridium ions at a pH ranging from 3 to 5.
