HYDROTHERMAL SYNTHESIS AND OPTICAL PROPERTIES OF CuInS2 MICRO-/NANOMATERIALS BY USING GEMINI SURFACTANT AS SOFT TEMPLATE
Abstract
We demonstrate in this paper the shape-controlled synthesis of CuInS2 micro-/nanoparticles through a facile hydrothermal method. Samples with different morphologies, i.e., nanoparticles and porous microspheres, are hydrothermally prepared in the presence of Gemini surfactant 1,10-bis(4-methyl-4-hexadecylpiperazine)decamethylene dibromide (Pi-16-10-16) as soft template. The products were characterized by using SEM, XRD, XPS, and EDS. Furthermore, the charge-discharge capability of the as-prepared CuInS2 samples is investigated by using the samples as the cathode in a lithium battery. The charge-discharge curves for the cells of CuInS2 exhibit higher initial discharge capacity showing a discharge capacity of 673 mAh/g,which is important for potential applications in photovoltaic (PV) and photoelectrochemical areas.
