MOF (Metal Organic Framework) compound with photothermal conversion performance as well as preparation method and application thereof
The invention relates to the technical field of adsorption materials for taking water from air, in particular to an MOF (Metal Organic Framework) compound with photothermal conversion performance and a preparation method and application thereof. According to the preparation method, MIL-101 (Cr) with high hygroscopicity is selected as the center of a core-shell structure, 2, 3, 6, 7, 10, 11-hexahydroxy triphenylene with a photothermal effect is taken as a ligand, Ni3 (HHTP) 2 is grown on the surface of the MIL-101 (Cr) in situ, and the MOF compound with the core-shell structure is obtained. The MOF compound disclosed by the invention not only can efficiently adsorb water molecules in air, but also can quickly heat after absorbing sunlight due to the unique photothermal effect of the MOF compound, so that the desorption process of the water molecules is promoted. Due to the photo-thermal performance of the MOF compound, the dependence on an external heat source is remarkably reduced, the energy consumption of the system is reduced, and the energy efficiency and economical efficiency of the whole water taking process are improved.
本发明涉及空气取水吸附材料技术领域，尤其涉及具有光热转换性能的MOF复合物及其制备方法与应用。本发明选择将具有高吸湿性的MIL‑101(Cr)作为核壳结构的中心，以具有光热效应的2,3,6,7,10,11‑六羟基三亚苯为配体，在MIL‑101(Cr)表面原位生长Ni3(HHTP)2，得到具有核壳结构的MOF复合物。本发明的MOF复合物不仅能够高效地吸附空气中的水分子，而且其独特的光热效应使其能够在吸收太阳光后迅速升温，从而促进水分子的脱附过程。本发明的MOF复合物的光热性能显著降低了对外部热源的依赖，减少了系统的能耗，提高了整个取水过程的能效和经济性。
