Abstract A visible-light catalytic composite material of regenerated cellulose supported SnS2 (SnS2/regenerated cellulose) was synthesized via microwave-assisted heating method at 120℃ with SnCl4 and thioacetamide as the source of Sn and S respectively. The obtained SnS2/regenerated cellulose was characterized by power X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-vis diffuse reflectance spectra (DRS) and specific surface areas (BET). The results show that the prepared SnS2 is a phase with hexagonal crystal structure and the composite exhibited a nano-sized lamellar structure with 0.52 nm of interlayer spacing. In comparison with the simple SnS2, the composite SnS2/regenerated cellulose has larger absorption band for visible light and specific surface area. Furthermore, the microwave heating method can greatly reduce the synthesis temperature and the reaction time. The composite prepared at 120℃ for 20~80 min exhibited excellent photocatalytic performance. The removal efficiency for Rhodamine B (20 mg/L) can reach 100% within 3 h by the composite under visible light irradiation, and the degradation ratio of RhB can still reach 88% by the composite even after five cycles of use/regeneration.
