Preparation and Photocatalytic Properties of SnO2/C/PPy Composites

SnO 2 /C(Carbon)/PPy composites have been prepared by in situ polymerization using SnO 2 /C nanomaterials as the matrix. The structures and properties of as-synthesized samples were characterized by XRD, FT-IR, XPS, BET, SEM and TEM. Meanwhile, the photocatalytic reaction mechanism of SnO 2 /C/PPy composite for degradation of Rhodamine B (RhB) was analyzed. The photocatalytic tests indicated that the SnO 2 /C/PPy composites have excellent photocatalytic activity for RhB degradation under visible light irradiation and the RhB can be degraded to 90% within 20 min. The photocatalytic activity is still outstanding after five cycles and as-synthesized samples have emerged as powerful foundation for further industrial application.
