摘要

Tin mono-sulphide (SnS) nanoparticles (Nps) have been successfully synthesised through ionic liquid assisted hydrothermal method using hydrated tin (Ⅱ) chloride as a precursor,thiourea as sulphur source precursors using 2-Methoxy ethyl methyl imidazolium methane sulfonate ionic liquid as co-solvent.The Reitveld refinement on powder X-ray diffraction (PXRD) confirmed the presence of orthorhombic SnS structure as major phase along with traces amount of SnS2 and Sn2S3.Diffuse reflectance spectrum studies revealed the energy band gap around 1.38 eV.TEM images confirmed the SnS Nps with average particle size of 40 nm and HRTEM suggest good crystallinity.The electrochemical property for lithium storage behaviour shows an initial discharge capacity of 658 mAh/g and it retains discharge capacity of 426 mAh/g for 16 cycles,at current density 100 mA/g.The obtained results indicate that SnS Nps to be one of the possible promising anode materials for next generation Lithium batteries.Photoluminescence study of SnS Nps shows a strong green emission at 530 nm.SnS Nps were also tested for the photocatalytic adsorption of methylene blue and Rhodamine B.
