Abstract

A thiol-functionalized MOF-808 was produced and used to remove mercury by post-synthetic modification using 6-mercaponicotinic acid (6mna). Parent MOF-808 was impregnated for varied periods of time in the 6mna solution to create modified MOF-808 materials, known as MOF-808-6mna-x, where x refers to the impregnation time. Diffraction and several spectroscopic techniques were employed to quantify and confirm the coordination of 6mna into MOF-808 framework. The amount of grafted 6man and the ability for adsorption of mercury (Hg) were shown to be linearly associated; the functionalized MOF-808-6mna-36 demonstrated improved Hg(II) removal, with an adsorption capacity of 250 mg/g.

硫醇功能化 MOF-808 的合成及其脱汞效率

通过使用 6-巯基烟酸（6mna）进行合成后改性，制备出硫醇官能化 MOF-808，并用于去除汞。将母体 MOF-808 在 6mna 溶液中浸渍不同的时间，可制成改性 MOF-808 材料，称为 MOF-808-6mna-x，其中 x 指浸渍时间。我们采用了衍射和多种光谱技术来量化和确认 6mna 与 MOF-808 框架的配位。结果表明，接枝 6man 的数量与吸附汞（Hg）的能力呈线性关系；功能化 MOF-808-6mna-36 对 Hg（II）的去除率有所提高，吸附能力达到 250 mg/g。

期刊介绍： Chemistry—An Asian Journal is an international high-impact journal for chemistry in its broadest sense. The journal covers all aspects of chemistry from biochemistry through organic and inorganic chemistry to physical chemistry, including interdisciplinary topics. Chemistry—An Asian Journal publishes Full Papers, Communications, and Focus Reviews. A professional editorial team headed by Dr. Theresa Kueckmann and an Editorial Board (headed by Professor Susumu Kitagawa) ensure the highest quality of the peer-review process, the contents and the production of the journal. Chemistry—An Asian Journal is published on behalf of the Asian Chemical Editorial Society (ACES), an association of numerous Asian chemical societies, and supported by the Gesellschaft Deutscher Chemiker (GDCh, German Chemical Society), ChemPubSoc Europe, and the Federation of Asian Chemical Societies (FACS).
