The synthesis of nanostructured Cu_2O was conducted in a non-aqueous solution via polyol method at a temperature of 130℃.It was found that the formation of Cu_2O nanobelts was heavily dependent on the presence of surfactant cetyltrimethylammonium bromide(CTAB).Cu_2O nanobelts with 100-400 nm in width and several micrometers in length were only observed when CTAB was used,whereas in other cases where CTAB was absent or CTAB was replaced with polyvinylpyrrolidone(PVP K-30),only spherical or cube-like particles were formed.The formation mechanism of Cu_2O nanobelts was discussed.
