Abstract

This paper presents a facile, room temperature and environmentally benign green route for the production of nanocrystalline CuS at 7 min by ultrasonic irradiating in aqueous solution of room temperature ionic liquid (RTIL), 1-ethyl-3-methylimidazolium ethylsulfate, ([EMIM][EtSO4]). The X-ray diffraction (XRD) studies display that the products are well crystallized in the form of hexagonal structure. Energy dispersive X-ray spectroscopy (EDX) investigations reveal that the products are extremely pure. The morphology of as-prepared nanoparticles was characterized by scanning electron microscopy (SEM). A possible formation mechanism for the production of nanoparticles in the aqueous solution of the RTIL with the aid of ultrasonic irradiation is proposed..
