Claim 17:
18. A method for making iridium oxide nanoparticles, comprising the 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 which is 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, and
wherein the molar ratio of the complexing compound to the iridium salt is controlled in the predetermined range such that once the oxidating agent is added, the iridium oxide nanoparticles are produced within 10 minutes.
