By using a facile and template-free polyol refluxing process, we reported the successful synthesis of porous SnS and SnS2 architectures on a large scale. The as-synthesized samples were characterized by using XRD, SEM, TEM, UV-vis DRS, Raman and N-2 adsorption-desorption analyses. Studies revealed that the as-synthesized SnS and SnS2 products mainly consist of porous flower-like microstructures with reasonable BET surface areas of 66 m(2) g(-1) and 33 m(2) g(-1), respectively. Photocatalytic properties of trace amounts of samples were investigated by photodegradation of MB and RhB under visible light irradiation. The photoelectrochemical properties of both samples were also studied by configuring the samples as photoelectrochemical (PEC) cells, exhibiting excellent photosensitivity and response with greatly enhanced I-on/off as high as 1.4 x 10(3), three orders of magnitude higher than previous work. The results indicate the potential applications of the SnSx nanostructures in visible-light-driven photocatalysts, high response photodetectors and other optoelectronic nanodevices.
