With the continual air pollution and environmental issues caused by the combustions of sulfur-containing fuels, the desulfurization in transport fuels becomes a crucial topic worldwide. In this study, a kind of phosphomolybdic ionic liquid–supported hydroxyapatite was successfully designed and employed as a catalyst for heterogeneous oxidative desulfurization in fuel. The prepared catalysts were characterized via Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and Brunauer–Emmett–Teller (BET), which confirmed that phosphomolybdic ionic liquid was successfully immobilized on hydroxyapatite. With the prepared sample n-[Pmim]PMo/HAP, the sulfur removal could reach 97.2% under mild conditions. Furthermore, the supported catalyst has excellent recyclability and utilization foreground.

由于含硫燃料的燃烧引起的持续的空气污染和环境问题，运输燃料中的脱硫成为世界范围内的关键话题。在这项研究中，成功​​设计了一种磷钼离子液体负载的羟基磷灰石，并将其用作燃料中非均相氧化脱硫的催化剂。制备的催化剂通过傅里叶变换红外光谱（FT-IR），X射线衍射（XRD）和Brunauer-Emmett-Teller（BET）进行了表征，证实了磷钼离子液体已成功固定在羟基磷灰石上。使用制备的样品n- [Pmim] PMo / HAP，在温和条件下脱硫率可达到97.2％。此外，负载型催化剂具有优异的可回收性和利用前景。
