多酸基主客体框架材料POMs@MOFs(COFs)

多酸具有组成、结构和尺寸易于调控的优点以及良好的电子储存和氧化还原能力,在催化、光电、磁等领域具有广阔的应用前景。特别是在催化领域,更是受到化学家们的青睐。多酸在催化反应过程中易团聚而导致失活,且比表面积较低,而将其引入到结构明确、多孔的框架材料中则能较好地解决以上问题。因此,该类材料已成为多酸化学领域的研究热点之一。本文按照多酸基主客体框架材料的合成方法,即原位合成法、浸渍合成法和机械研磨合成法来进行分类,并分别讨论了其优缺点。并进一步总结了该类材料在催化、染料吸附降解、质子传导以及光电传感等领域的性能和应用,并对其未来发展趋势进行了展望。

Polyoxometalate-Based Host-Guest Framework Materials POMs@MOFs(COFs)

Due to the advantages of their easy regulated composition, structure and size along with the excellent electronic storage and redox activity, polyoxometalates have broad application prospects in the fields of catalytic, photoelectric, and magnetic, etc. It is much favored by chemists especially in the field of catalysis. Polyoxometalates are easy to deactivate due to the agglomeration in the catalytic process, and its specific surface area is low. The introduction of polyoxometalates into a well-structured, porous framework material can better solve the above problems. Therefore, these materials have become one of the research hotspots in the field of polyoxometalates chemistry. In this paper, the polyoxometalate-based host-guest framework materials are classified according to their synthetic methods, namely in situ synthesis, impregnation synthesis and mechanical grinding synthesis, and their advantages or disadvantages are discussed separately. We further summarize the performance and application of these materials in the fields of catalysis, dye adsorption and degradation, proton conduction and photoelectric sensing, and prospect its future development trend.
