摘要:

二维(2D)层状材料因其独特的性质在燃料油氧化脱硫领域应用广泛,如石墨烯和类石墨烯材料(如类石墨相氮化碳和六方氮化硼等)、2D硅基材料、层状双金属氢氧化物、MXene、2D金属有机骨架材料、二硫化钼等。本文从不同2D层状材料出发,综述了如何构建催化氧化脱硫催化剂、催化剂脱硫效率以及脱硫过程和机制,并对2D层状材料在氧化脱硫领域的研究现状进行了梳理。然而,普通的2D层状材料大多因为材料本身的催化性能不足,不能直接应用于燃料油氧化脱硫工艺。因此,研究人员通过制造缺陷、元素掺杂、官能团改性和负载活性位点等方法对2D层状材料进行改性并将其应用于催化氧化脱硫工艺。最后,本文对2D层状材料在氧化脱硫领域的研究方向提出了展望,指出了构建具有可控、开放2D传输孔道的2D层状氧化脱硫催化剂是未来脱硫领域研究的重要方向之一。

Abstract:

Two dimensional (2D) layered materials are widely used in the field of oxidative desulfurization of fuel oil due to their unique properties, such as graphene and other graphene-like materials (such as graphitic carbon nitride and hexagonal boron nitride), 2D silicon-based materials, layered double hydroxides, MXene, 2D metal-organic frameworks, molybdenum disulfide, etc. Starting from different 2D layered materials, this paper summarized how to build catalytic oxidation desulfurization catalysts, catalyst desulfurization efficiency, desulfurization process and mechanism, and combed the research status of 2D layered materials in the field of oxidative desulfurization. Nevertheless, most ordinary 2D layered materials cannot be directly applied to fuel oil oxidation desulfurization process because of their insufficient catalytic performance. Therefore, researchers modified 2D layered materials by manufacturing defects, element doping, functional group modification and loading active sites, and applied them to catalytic oxidation desulfurization process. Finally, this article presentes prospects for the research direction of 2D layered materials in the field of oxidative desulfurization, and pointes out that constructing 2D layered oxidative desulfurization catalysts with controllable and open 2D transport channels was one of the important directions for future research in the field of desulfurization.

Key words: two-dimensional materials, fuel oil, catalysis, oxidative desulfurization, two-dimensional channels
