比较了单壁碳纳米管和少层石墨烯片的界面吸附行为。在水/1，2-二氯乙烷界面处观察到碳纳米管的强吸附，而石墨烯分散体的吸附较弱。发现向有机相中添加电解质对石墨烯的吸附具有强烈的影响。一个简单的表面能模型并不能完全解释这些观察结果，而残余电荷及其分布似乎是这种吸附行为差异背后的关键因素。吸附在液-液界面上的碳纳米材料可以起到双极电极的作用：对金属改性石墨烯颗粒氧化1，2-二氯苯进行了初步研究。(C)2019爱思唯尔有限公司版权所有。
The interfacial adsorption of single-walled carbon nanotubes and few-layer graphene flakes, prepared by solution phase exfoliation, is compared. Strong adsorption of carbon nanotubes was observed at the water/1,2-dichloroethane interface, while a weaker adsorption of the graphene dispersion was seen. Addition of electrolyte to the organic phase was found to have a strong effect on the adsorption of graphene. A simple surface energy model does not fully explain these observations, rather residual charges and their distribution appears to be the key factor behind this difference in adsorptive behaviour. Carbon nanomaterials adsorbed at the liquid-liquid interface can function as bipolar electrodes: a preliminary investigation of the oxidation of the 1,2-dichlorobenzene by metal-modified graphene particles is performed.
