Cu2o/Alzn-Ldh Preparation on Fto Electrode Substrate For Enhanced Water Oxidation

The electrochemical activity of the cu2o/alzn-ldh, deposited on the fto electrode, was investigated in naoh (0.1 m) media. the thin film cu2o/alzn-ldh was characterized by techniques such as x-ray diffraction (xrd), scanning electron microscopy (sem), and energy-dispersive x-ray spectroscopy (edx). based on the obtained results from xrd, cu2o/alzn-ldh was prepared in the nanometer size with good crystalline quality. the sem images were shown the synthesis of a thin film cu2o/alzn-ldh nanocomposite on the fto electrode. the water oxidation results show that cu2o-zn/al-ldh modified fto electrode is an improved electrocatalyst and has high activity at water oxidation in alkaline media with the onset potential about 0.6 v vs. sce and overpotential of 380 mv at10 ma/cm. the improved water oxidation activity at cu2o/alzn-ldh can be attributed to the good conductivity of the nanocomposite.
