Chromium-based MIL-101 and graphite oxide (GO) composite ([email protected]) was synthesized and applied for adsorption performances toward a series of aromatics (benzene, toluene, and ethylbenzene). Desorption activation energies of aromatics on this composite were evaluated based on temperature-programmed desorption (TPD) experiments. The results indicated that the aromatic uptakes on the composite increase with the carbon number at low pressure. In contrast, at high pressure, their adsorption capacities exhibit an opposite trend. The composite possesses high uptakes of the aromatics, which are approximately 1.8–6.0 times higher compared with conventional adsorbents. The desorption activation energies of the aromatics increase with the carbon number of aromatics. Additionally, the adsorption of ethylbenzene on the composite is highly reversible. More importantly, the [email protected] composite exhibits enhanced thermal conductivity up to 0.369 W/mK at 303 K. The [email protected] composite with high adsorption capacity, enhanced thermal conductivity, and efficient recyclability provided a promising candidate for practical applications in field of volatile organic compounds adsorption.

新型铬基[受电子邮件保护的]氧化物复合材料上芳烃的增强吸附性能
合成了铬基MIL-101和氧化石墨（GO）复合材料（[受电子邮件保护]），并将其用于吸附一系列芳族化合物（苯，甲苯和乙苯）。根据程序升温脱附（TPD）实验评估了该复合材料上芳烃的脱附活化能。结果表明，在低压下，复合材料上芳烃的吸收随碳原子数的增加而增加。相反，在高压下，它们的吸附能力呈现相反的趋势。该复合材料具有较高的芳烃吸收率，是传统吸附剂的约1.8-6.0倍。芳族化合物的解吸活化能随芳族化合物的碳原子数增加而增加。另外，乙苯在复合材料上的吸附是高度可逆的。
