Sonochemical synthesis of crystalline CuS nanoplates via an in situ template route

Single crystalline CuS nanoplates with average sizes of about 20–40 nm have been successfully synthesized without any surfactant by a sonochemical approach under ambient conditions. Cu(OH)2 nanoribbons were firstly used as the copper source and in situ template to prepare CuS nanostructure. The possible mechanism of the formation of CuS nanoplates was discussed.
