Synthesis of CuO Wires from Layered Organic-Inorganic Hybrids

摘要

Copper oxide (CuO) is a narrow band-gap semiconducting oxide that has been widely studied in electrochemical cells,in photothermal and photoconductive materials,and as a heterogeneous catalyst.Various techniques have been used to fabricate CuO nanostructures.One-dimensional (1D) CuO can be obtained through thermal treatment by using the precursors Cu(OH)_2 or Cu_2(OH)_2CO_3 as a sacrificial template.Layered organic-inorganic hybrids are characterized by strong intralayer covalent or ionic bonding in an inorganic frame,and weak interlayer interactions such as van der Waals forces between organic molecules.Most layered organic-inorganic hybrid materials fabricated to date were obtained by intercalation of organic molecules into the inorganic layer.In this work,we report the preparation of CuO from the layered organic-inorganic hybrid,Cu_2(OH)_3(C_(12)H_(25)SO_4).CuO wires are formed by a self-aggregation of nanoparticles.The morphologies of the aggregated CuO products are analyzed using scanning electron microscopy and transmission electron microscopy.
