摘要
In this paper, we report synthesis of novel nanoparticle catalyst of iridium oxide supported on carbon nanotube (IrO2/CNT) and characterization of activity and durability for oxygen evolution reaction (OER). The IrO2/CNT catalyst was prepared from iridium complex and COOH-CNT by hydrothermal method. The synthesized IrO2/CNT catalysts was characterized by transmission electron microscopy, x-ray diffraction, Raman microscopy, Fourier transfer-infrared spectroscopy, x-ray photoelectron spectroscopy, thermogravimetric analysis and electrochemical methods. The average particle size of the IrO2 particles on CNT is 1.7 nm and the loading amount of IrO2 is 4 wt%. The XPS measurement reveals that Ir complex was completely converted to iridium oxide through hydrothermal treatment. The IrO2/CNT catalyst showed sufficient performance for OER activity and durability in sulfuric acid solution. Our results indicate that IrO2/CNT is one of the prospective candidate catalysts for water electrolyzer.
