金属组分引入对埃洛石纳米管吸附脱硫性能的影响

摘要

通过等体积浸渍法将金属组分引入到埃洛石纳米管（HNTs）上，研究金属组分对HNTs吸附脱硫性能的影响。采用X射线衍射（XRD）、吡啶吸附红外光谱（Py-IR）和N₂吸附-脱附测试对改性材料进行表征和分析。研究发现，3种金属组分在HNTs上主要以氧化物的形式存在，而且Co₃O₄、NiO和CuO的引入均能提高HNTs的吸附脱硫性能，其中负载量为10% NiO的HNTs脱硫率提高最多，由原管的30.10%提高到47.51%。金属氧化物的引入使HNTs表面的Lewis酸量增加，进而提高了HNTs的吸附脱硫性能。因此表明HNTs表面的Lewis酸量是影响其吸附脱硫性能的重要因素。

Abstract：

The study was to investigate changes in the adsorption desulfurization performance of halloysite nanotubes(HNTs) with the introduction of metal components by incipient wetness impregnation. The samples were characterized by X-Ray diffractometer(XRD), adsorbed pyridine infrared spectroscopy(Py-IR) and N₂-sorption. The experimental results showed that three kinds of metal components were mainly presented as their oxides on HNTs, and Co₃O₄, NiO and CuO can all improve the adsorption desulfurization performance of HNTs, and the desulfurization rate of HNTs with 10% NiO increased the most, from 30.10% to 47.51%. Metal oxides improved the amount of Lewis acid on the surface of HNTs, and the adsorption desulfurization performance of HNTs increased with the change of the amount of Lewis acid. Therefore, the amount of Lewis acid on the surface of HNTs is an important factor affecting the adsorption desulfurization performance of HNTs.
