In the last few decades, Tin (II) sulphide (SnS) driven by its unique properties being low cost, lack of toxicity and its abundance in nature, has received great recognition in a majority of applications such as photocatalysis and photovoltaics. Single-crystals SnS has been synthesis and modified in various ways with the aim of improving in its efficiency which as of now is still relatively low. Some of the modification techniques involve reducing the particle size and/or forming a composite with other materials. In this study, single crystal SnS with an indirect bandgap of 0.92-1.07 eV was synthesized at different temperatures. The structure of this material, composition, and optical properties of the as-synthesized SnS were characterized by XRD spectroscopy, SEM images, UV–vis spectra. The as-synthesized SnS material showed good photocatalytic activity in the degradation of MB under visible light (LED) with rate constant of 3.943x10-3 min-1 which was attributed to the bandgap of the material. To improve on this activity another synthetic method was used to synthesis, SnS nanoflower with a direct bandgap of 1.55 eV via a wet chemical method. This material showed enhanced activity for the degradation of MB (rate constant = 6.5625 x10-3 min-1) which was about 2 times higher than that of SnS powder. Using RhB the results were even more staggering, SnS powder had a rate constant of 6.1115 x10-4 min-1 that was about 10times less for SnS nanoflower (7.1994 x10-3 min-1). This difference was owing to the change in morphology and large specific surface area due to the size difference. SnSNS/SnS2NS composite was also synthesis through facile ultrasonic exfoliation of bulk SnS and SnS2 in N-methyl-2-pyrrolidone (NMP). The SnSNS/SnS2NS composite had activity for the degradation of MB 1.01 x10-2 min-1 which was higher than pure SnS and pure SnS2 under visible light irradiation. The particle size and the low recombination rate was suggested to be the factors behind the increase in the rate constant.
