Abstract Graphene oxide–titanium dioxide (GO@TiO2) nanocomposite with mean diameter size of 14 nm has been fabricated, characterized, and used as photocatalyst for degradation of two highly toxic insecticides, namely carbaryl and imidacloprid. Characterizations of GO@TiO2 have been carried out using various analytical and spectroscopic techniques. Compared to TiO2NPs, the fabricated GO@TiO2 nanocomposite has advantage of its smaller band gap. The finding that the photocatalytic degradation of the examined insecticides by the fabricated GO@TiO2 is more efficient compared to that of TiO2NPs suggests the superiority for using the fabricated GO@TiO2 nanocomposite for degradation of the examined toxic insecticides.

用于降解一些有毒杀虫剂的氧化石墨烯-二氧化钛纳米复合材料的制备和表征

摘要 制备、表征了平均直径为 14 nm 的氧化石墨烯-二氧化钛 (GO@TiO2) 纳米复合材料，并将其用作降解两种剧毒杀虫剂甲萘威和吡虫啉的光催化剂。已经使用各种分析和光谱技术对 GO@TiO2 进行了表征。与 TiO2NPs 相比，制备的 GO@TiO2 纳米复合材料具有带隙较小的优点。与 TiO2NPs 相比，制造的 GO@TiO2 光催化降解所检测杀虫剂的发现表明使用制造的 GO@TiO2 纳米复合材料降解所检测的有毒杀虫剂具有优越性。
