摘要:

二维纳米材料层状硅酸镍(Ni-PS)具有片层结构规则有序、比表面积高和层间性能可调等优点,作为功能材料在磁、电及催化等领域具有广泛的应用前景。本文在综述了Ni-PS的合成机理和制备方法的基础上,介绍了引入有机Si源、利用金属离子(或氧化物)进行掺杂、合成纳米管以及与碳基材料进行复合等手段来调控Ni-PS的结构和性能,详细阐述了Ni-PS或作为前体在制备高质量金属纳米粒子、电极材料、磁性载体和重金属离子吸附剂等方面的应用,着重指出Ni-PS的独特层状结构能够在还原过程中限制金属扩散和保护纳米粒子不被氧化和烧结长大,可用于制备新型高效Ni基催化剂,被广泛应用于制合成气、催化制氢/加氢及分子链催化重构等。最后,提出了Ni-PS在材料领域的发展方向和建议:深入研究Ni-PS的合成技术和改性方法,制备高性能、多功能Ni-PS及复合材料,进一步拓展其在功能材料和工程材料领域的应用。

Abstract:

Due to its ordered lamellar structure, high specific area and adjustable structural properties, the 2-D layered nanomaterial of nickel phyllosilicate (Ni-PS) has been received much attention as the functional materials in the magnetic, electrical and catalytic fields. This paper reviewed the recent progress on the synthetic mechanism and fabrication approaches of Ni-PS firstly, and then a number of useful modification strategies, including utilization of organic silicon sources, metal-ions/oxides doping, synthesizing nanotubular and compositing with carbon materials, which can improve the structure and performance of Ni-PS, were presented as well. The applications of Ni-PS or as a precursor in the formation of high-quality metallic nanoparticles, electrode materials, magnetic carriers and absorbers for heavy metal ions were described in detail. In particular, Ni-PS was very popular in preparing the novel and high-effective nickel-based catalysts thanks to its characteristic laminated structures which restrained the diffusion of nickel atoms as well as provided protection to the nanoparticles from oxidation and sintering during the reduction process. The resulted catalysts were widely used for the preparation of syngas, hydrogen production, hydrogenation reaction and chemical looping reforming, etc. Finally, it was suggested that much attention should be paid on the fabrication and modification of Ni-PS to generate high performance and multi-functional Ni-PS and the composites, promoting their applications in the functional and engineering materials.

Key words: nickel phyllosilicate(Ni-PS), synthetic methods, modifications, precursor, electrode materials, magnetic carriers, nickel based catalyst
