Abstract: There are provided a monocrystalline copper oxide (I) nanowire array manufacturing method using low-temperature electrochemical growth, and more particularly, to a manufacturing method allowing easy vapor deposition at low temperatures and also a monocrystalline copper oxide (I) nanowire array manufacturing method using low-temperature electrochemical growth which retains characteristics such as large-area growth, high-crystallinity nanowire, uniform radial distribution, easy length, radius adjustment, and the like. A monocrystalline copper oxide (I) nanowire array manufacturing method of the present invention includes a step of manufacturing a nanopore alumina layer (anodized alumina (AAO)) from a high-purity aluminum (Al) sheet by using a two-step anodic oxidation method; and a step of manufacturing a monocrystalline copper oxide (I) nanowire array by using the nanopore alumina layer as a nanopore molding flask by means of a low-temperature electrochemical growth method.
