A robust synthesis of iridium oxide (IrO2) nanoclusters using methanol as a reducing agent via the chemical reduction method is reported in this article. Polyvinylpyrrolidone (PVP) and polyoxyethylene(23) lauryl ether (POLE) were used as stabilizers. The formation of IrO2 nanoclusters was confirmed by the appearance of new absorption peak at 230 nm in UV-vis spectra. XRD and TEM were used to determine the degree of crystallinity and size of nanoclusters, respectively. Further characterization studies were carried out by FT-IR spectroscopy to investigate the coordination between IrO2 nanoclusters and stabilizers. |
