Structure of Antimony Sulfoiodide Ultrasonically Prepared in Carbon Nanotubes

Abstract

This paper presents a brand new hybrid material on the nanometric scale: the antimony sulfoiodide (SbSI) within carbon nanotubes (CNTs). It was prepared in CNTs ultrasonically by using elemental antimony (Sb), sulfur (S) and iodide (I) in the presence of methanol under ultrasonic irradiation (34 kHz, 2.6 W/cm2). The sonochemical process was leaded for 3 hours at 323 K. The antimony sulfoiodide (SbSI) consisted in multiwalled carbon nanotubes (CNTs) were characterized high-resolution transmission electron microscopy (HRTEM). These investigations exhibit that the SbSI filling the CNTs has single-crystal structure in nature and in the form of multiwalled carbon nanotubes. The SbSI grown in CNTs are very promising materials for further investigations as well as for some industrial and medical applications.

Carbon Nanotubes Filled With Ternary Chalcohalides

“…This review summarizes results of recent investigations [11][12][13][14] of carbon nanotubes (CNTs) filled with ternary chalcohalides formed from the group 15-16-17 elements, i.e. antimony sulfoiodide (SbSI) and antimony selenoiodide (SbSeI) known as SbSI-type materials.…”

“…Both SbSI and SbSeI were prepared in CNTs ultrasonically from the constituents (the elements Sb, I, and S or Se) [11][12][13][14]. Methanol and ethanol served as the solvents for these reactions, respectively.…”

“…Characterization of the multi-walled CNTs filled with SbSI or SbSeI [11][12][13][14] was accomplished using different techniques, such as powder X-ray diffraction (XRD) performed on a JEOL JDX-7S X-ray diffractometer with graphite monochromatized Cu K α radiation (λ = 0.154056 nm), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) performed on a Hitachi S-4200 microscope with EDS Thermo Scientific spectrometer, high-resolution transmission electron microscopy (HRTEM) and selected area electron diffraction (SAED) performed on a JEOL-JEM 3010 microscope. The powder XRD patterns of dried multi-walled CNTs filled with SbSeI ultrasonically in ethanol with different compositions of the reactants [14] (1-0.101 g Se, 2-0.202 g Se, 3-0.404 g Se; 0.156 g Sb, 0.165 g I 2 , and 0.102 g of CNTs in 10 ml absolute ethanol; described peaks correspond to the crystalline SbSeI [27,28], C [29,30] and SbI 3 [31,32]).…”
