Hydrothermal synthesis, characterization and optical properties of SnS prismatic nanorods

One dimensional nanostructures have been considered promising candidates for optoelectronics and energy storage devices. However, cost effective approach for large scale production using wet chemical method is still a big challenge. Here, single crystalline monodispersed stannous sulfide (SnS) nanorods in the range of 400 nm to micrometer have been synthesized using solution based method. The morphology of the prepared nanorods was controlled by tuning the parameters, including the concentrations of reagents, reaction time and temperature. The resultant nanorods were characterized using XRD, FESEM, TEM, PL and Raman spectroscopy techniques. Three modes 160.2, 190 and 213.6 cm(-1) were observed by Raman spectroscopy, which are consistent with nano orthorhombic SnS herzenbergite phase. Addition, hydrogen absorption characteristics of SnS nanorods performed at 373 K shows a good absorption capacity of 0.82 wt%. (C) 2017 Published by Elsevier B.V.
