摘要 对Ti3AlC2进行氢氟酸(HF)腐蚀剥离,获得不同剥离程度的二维Ti3C2材料。利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)等对不同剥离时间获得的样品晶体结构和微观形貌进行表征,采用紫外分光光度计测试其作为吸附剂对阳离子型亚甲基蓝(MB)和阴离子型刚果红(CR)有机染料的吸附性能,从吸附动力学和热力学角度分析吸附机理。结果表明:随着HF腐蚀剥离时间的延长,二维Ti3C2材料片层间距增加,对阳离子型亚甲基蓝、阴离子型刚果红有机染料均表现出较好的吸附性能,并符合准二级吸附动力学模型以及Langmuir和Freundlich吸附等温线拟合模型,说明该吸附过程是以化学吸附为主要吸附机制、单分子和多分子吸附模式共同作用、协同吸附的过程,并因阴阳离子染料的不同,作用机理不同,表现差异性吸附行为。

Abstract:Two-dimensional Ti3C2 was obtained by etching Ti3AlC2 in hydrofluoric acid(HF) for different time. The phase composition and morphology of the as-obtained samples were characterized by X-ray diffraction patterns(XRD), scanning electron microscopy (SEM). The adsorption behaviour for a cationic dye methylene blue(MB) and anionic dye Congo red(CR) was tested by ultraviolet spectrophotometer, and then the adsorption kinetics and thermodynamics were investigated. The results show that with the elongation of the corrosion time in hydrofluoric acid, the spacing of the two-dimensional Ti3C2 material is increased accordingly. The results show that the etched Ti3C2 exhibits good adsorption performance for MB and CR, both fitting well with the quasi secondary adsorption model, whereas the adsorption thermodynamics fits well with Langmuir and Freundlich adsorption isotherm model, respectively, suggesting that the adsorption is an process dominated by chemical adsorption mechanism and the joint action of mono- and multimolecular adsorption modes. Based on the difference of cationic and anionic dye, the mechanism of action is different, and thus exhibiting different adsorption behaviours.
