Outstanding adsorption performance of graphene–carbon nanotube aerogels for continuous oil removal,Carbon 80(2014)523-533. 影響因子:6.16 摘要:We report a green approach for synthesis of graphene–carbon nanotube aerogels with three dimensional (3D) interconnected networks prepared from natural graphite rocks. A one-step reaction under the synergic effects of the reduction of graphene oxide (GO) sheets and acid treated carbon nanotubes (CNTs) by ferrous ion is employed eliminating the use of harsh chemicals for the reduction of GO. CNTs are incorporated into the network to increase the robustness and hydrophobicity of aerogels with excellent porosity and oleophilic properties. The prepared aerogels exhibit outstanding adsorption performance for the removal of petroleum products, fats and organic solvents especially under continuous vacuum regime showing adsorption capacity of 28 L of oil per gram of aerogel. The proposed syntheticmethod is simple and economical for the scalable production of highly porous 3D graphene–carbon nanotube aerogels, which can be successfully used for efficient and cost-effective oil spill clean-up and water purification. 中文翻譯摘要:我們報道了一種綠色的方法合成石墨烯-碳納米管氣凝膠用由天然石墨巖石制備的3D連通的網(wǎng)絡(luò)。還原氧化石墨烯(GO)片和用亞鐵離子酸處理碳納米管(CNTs)協(xié)同作用的第一步反應(yīng)是消除用于還原GO的刺激性化學物質(zhì)。CNTs并入網(wǎng)絡(luò)中提高氣凝膠的穩(wěn)定性和疏水性,其具有高的氣孔率和親油特性。制備的氣凝膠呈現(xiàn)很好的吸附性能用于石油產(chǎn)品、動植物油和有機溶劑的去除,特別是在連續(xù)真空條件下每克碳氣凝膠可以吸附28L油。所提到的合成方法是簡單的、經(jīng)濟的用于合成高孔隙率的3D石墨烯-碳納米管氣凝膠產(chǎn)品的衍生物,可以應(yīng)用到漏油和水凈化領(lǐng)域。 想獲得更多資源可點擊鏈接http://www.tjdrfk.com/news 5.jpg 1.jpg 2.jpg 3.jpg 4.jpg |
