Abstract

A new way of synthesizing nanoscale copper oxide particles is described in this work. Oxides of an intermediate metal, such as copper oxide, can be used as an effective semiconductor in the photocatalytic reactions once they are prepared in a special way. The CuO nanorods were synthesized electrochemically under surfactant-free, static conditions. The obtained nanorods have an average length of less than 50 nm. The CuO nanorods were used as a heterogeneous catalyst in an aqueous medium. 2,4-Dichlorophenol (DCP) was used as a probe molecule. The CuO nanorods showed an excellent ability to degrade DCP under visible light and without the need for any auxiliary oxidizing agent.
