Influence of Solution pH on the Electrochemical Fabrication of Functional Metal Oxides Using a Nanoporous Alumina Template
E-mail:
We have investigated the influence of solution pH on the electrochemical fabrication of functional metal oxides, i.e., cuprous oxide (Cu2O) and zinc oxide (ZnO), using a nanoporous alumina template. At a low solution pH of ca. 5 ~ 7, Cu metal was preferentially filled into an alumina template; Cu2O nanorods were formed at solution pH above 8~ 10. In the preparation of ZnO using a zinc nitrate solution with a bulk solution pH of 4.3, a ZnO thin film prepared through remote electro-precipitation was observed on the alumina template.
