MXene/MFe2O4异质结构控制合成及吸波性能研究

摘要尖晶石铁氧体（化学式MFe2O4 M=Co、Ni、Zn等）因为其优秀的物理化学性质而受到各界广泛关注。诸如高磁导率、磁特性很软、对称性高、低损耗等特性，使其在催化、吸附、信息存储等领域被广泛应用。但MFe2O4也存在不少缺陷，密度高、容易团聚、导电性差，这些问题严重影响了其优异性能的发挥。目前，MFe2O4与Graphene相结合形成二维吸波材料是较好的应用方向，然而MXene表现出了比Graphene更好的性质，它的比表面积更大，而且是多层材料，在与其他材料的复合中也有着良好的表现，两者的结合可能是更好的选择。本文用水热法合成MFe2O4粉体，通过控制其合成温度与合成时间来得到最佳合成条件。本文通过用HF酸腐蚀Ti3AlC2来制取Ti3C2粉体，本文通过加入不同比例Ti3C2粉体至MFe2O4溶液中，观察其对磁性能的影响。 79744

Abstract Spinel ferrite (chemical formula MFe2O4M = Co, Ni, Zn, etc。) because of its excellent physical and chemical properties and widespread concern。 Such as high magnetic permeability, magnetic properties are very soft, high symmetry, low loss and other characteristics, so that in the catalytic, adsorption, information storage and other fields are widely used。 However, MFe2O4 also has many defects, high density, easy agglomeration, poor conductivity, these problems seriously affect the excellent performance of its play。 At present, MFe2O4 and Graphene combine to form a two-dimensional absorbing material is a good application direction, but MXene showed better properties than Graphene, its larger surface area, and multi-layer material, with other materials Composite also has a good performance, the combination of the two may be a better choice。 In this paper, MFe2O4 powder was synthesized by hydrothermal method, and the optimum synthesis conditions were obtained by controlling the synthesis temperature and synthesis time。 In this paper, Ti3C2 powder was prepared by etching Ti3AlC2 with HF acid。 The effect of Ti3C2 powder on the magnetic properties was observed by adding different Ti3C2 powder into MFe2O4 solution。
