以阵列二氧化钛纳米棒为载体制备一体化析氧电极
Preparation of integrated oxygen evolution electrode using array of titanium dioxide nanorods as carrier
摘要
Abstract
The impregnation thermal decomposition method was successfully used to prepare IrO2-TiO2/C oxygen evolution electrode with chloro iridic acid as a precursor, carbon paper as support, the array of TiO2 nanorods as the carrier. Scanning electron microscopy (SEM), XRD, XPS and electrochemical methods——cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were used to study the effect of the morphology of the carrier on the performance of oxygen evolution electrode. The results show that the titanium dioxide carrier can effectively inhibit corrosion of the supporting body of carbon paper under high potential; integral charge of the integrated oxygen evolution electrode increases from 87.2 mC/cm2 to 178.5 mC/cm2,and electrochemical reaction resistance reduces from 3.13Ω·cm2 to 1.62Ω·cm2 when voltage is 2.4 V and polarization current is 13.2 mA/cm2, which greatly improves the oxygen evolution electrode contact area and electrocatalytic activity.关键词
