제목 Clean and Facile Synthesis of Reduced Graphene Oxide-SnO2 Nanocomposites and Its Enhanced Photocatalytic Activities
초록 A facile way has been developed for synthesis reduced graphene oxide-SnO2 nanocomposites in ionic liquid with the assistance of microwave irradiation without any additional reducing agent. The formation of SnO2 nanoparticles with tetragonal structure has been proved by X-ray diffraction patterns. From field emission scanning electron microscope and transmission electron microscopy results, graphene sheets were uniformly decorated with SnO2 nanoparticles with an average size of around 4-5 nm in diameter. The photocatalytic activities of as-prepared nanocomposites for degradation of methylene blue under UV irradiation have been investigated. As a result, reduced graphene oxide-SnO2 nanocomposites tend to have much higher photocatalytic activity than pure SnO2 nanoparticles.
