摘要

卵壳纳米反应器在提高催化性能方面具有诸多优势。这项工作展示了利用金属有机框架制备卵黄壳 Fe3O4@SiO2/Al2O3-T(T = 500-900℃)的过程。表征结果表明,获得的纳米反应器具有 Fe3O4 卵黄和 SiO2/Al2O3 外壳。对照实验结果表明,Fe3O4@SiO2/Al2O3-800 在糠醛缩醛生成 2-(二甲氧基甲基)呋喃的过程中表现出优异的性能,在 60 ℃、常压条件下,5 h 内的产率达到 97%。此外,多孔的 SiO2/Al2O3 壳有利于传质,增加了活性位点的可及性,也有助于提高性能和稳定性。

MOF-derived Fe3O4@SiO2/Al2O3 yolk-shell nanoreactor for efficient furfural acetalization

Yolk-shell nanoreactors feature numbers of advantages in promoting catalytic performance. This work demonstrates the fabrication of yolk-shell Fe3O4@SiO2/Al2O3-T (T = 500–900 °C) from metal-organic framework. Characterizations indicate the Fe3O4 yolk and SiO2/Al2O3 shell of the obtained nanoreactors. Fe3O4@SiO2/Al2O3–800 showed excellent performance in furfural acetalization to 2-(dimethoxymethyl)furan, achieving a 97% yield at 60 °C, atmospheric pressure within 5 h. Control experiments reveal the high reactivity of Fe3O4 yolks for furfural acetalization, and acidic Al species are favorable for reactivity promotion. Besides, porous SiO2/Al2O3 shells facilitate mass transfer and increase the accessibility of active sites, also contribute to the high performance and stability.
