摘要

本研究采用改良的超声化学法制备了一种纳米结构的石墨烯-二氧化钛纳米复合材料，然后在 400 ºC 煅烧，并通过 X 射线衍射、透射电子显微镜、紫外可见光谱、红外光谱和 X 射线光电子能谱对其进行了表征。通过光催化降解甲基橙染料，对制备的样品的光催化活性进行了评估。分析发现，纳米复合材料的可见光吸收率比纯二氧化钛高。所制备的 GT2 复合材料在阳光照射下的降解效率约为 75%。

Combination of Sonochemical Synthesis and Calcination of Graphene-TiO2 Nanocomposite for Efficient Photocatalytic Degradation of Methyl Orange Dye

In this work, a nanostructured graphene-TiO2 nanocomposite was prepared by modified sonochemical method followed by calcination process at 400 ºC and characterized by X-ray diffraction, transmission electron microscopy, UV visible spectroscopy, IR spectroscopy and X-ray photoelectron spectroscopy. The photocatalytic activity of the prepared sample was evaluated by photocatalytic degradation of methyl orange dye. On analysis, visible light absorption was found to be increased for the nanocomposite rather than pure TiO2. About 75% degradation efficiency was exhibited by the prepared GT2 composite under sunlight irradiation.
