Abstract

Preferential orientation control of metal–organic framework (MOF) films is advantageous for maximizing pore uniformity and minimizing grain-boundary defects. Nonetheless, the preparation of MOF films with both in-plane and out-of-plane orientations remains a grand challenge. In this study, we reported the preparation of three-dimensionally oriented MIL-96 layers through combining morphology control of MIL-96 seeds with addition of polyvinylpyrrolidone surfactants and arachidonic acids. The three-dimensionally oriented MIL-96 film was readily obtained through in-plane epitaxial growth. It is anticipated that the aforementioned protocol can be effective for obtaining diverse MOF films with a three-dimensionally oriented organization.

六边形 MIL-96 微板的三维定向组织,实现卓越的薄膜微观结构
金属有机框架(MOF)薄膜的优先取向控制有利于最大限度地提高孔隙均匀性和减少晶界缺陷。然而,如何制备具有平面内和平面外取向的 MOF 薄膜仍然是一个巨大的挑战。在本研究中,我们报道了通过对 MIL-96 种子进行形态控制,并添加聚乙烯吡咯烷酮表面活性剂和花生四烯酸,制备出三维取向的 MIL-96 层。通过面内外延生长,很容易获得三维取向的 MIL-96 薄膜。预计上述方案可以有效地获得具有三维取向组织的各种 MOF 薄膜。

期刊介绍: The Chinese Journal of Chemical Engineering (Monthly, started in 1982) is the official journal of the Chemical Industry and Engineering Society of China and published by the Chemical Industry Press Co. Ltd. The aim of the journal is to develop the international exchange of scientific and technical information in the field of chemical engineering. It publishes original research papers that cover the major advancements and achievements in chemical engineering in China as well as some articles from overseas contributors. The topics of journal include chemical engineering, chemical technology, biochemical engineering, energy and environmental engineering and other relevant fields. Papers are published on the basis of their relevance to theoretical research, practical application or potential uses in the industry as Research Papers, Communications, Reviews and Perspectives. Prominent domestic and overseas chemical experts and scholars have been invited to form an International Advisory Board and the Editorial Committee. It enjoys recognition among Chinese academia and industry as a reliable source of information of what is going on in chemical engineering research, both domestic and abroad.
