Abstract
By using terephthalic acid, 2, 5-furandicarboxylic acid, and terbium nitrate
hexahydrate, a Tb-MOF with a core-shell structure was successfully designed and prepared.
A one-pot method was employed to design and synthesize core-shell Tb-MOF. The
morphology, luminescence performance, and stability were well characterized.
Tb-MOF demonstrated good water stability, acid and alkali resistance, and thermal stability.
Tb-MOF was found to have high sensitivity to detect Cr3+, Bi3+, and acetone in an aqueous solution,
and the LOD of Cr3+, Bi3+, and acetone were calculated to be 0.18 μM, 4.22 μM, and 0.26%,
respectively. The sensing mechanism of Cr3+ and acetone was explained as energy-competitive
absorption, and the sensing mechanism of Bi3+ was explained as ion replacement.
The prepared Tb-MOF can be developed as a multifunctional light-emitting sensor with
high selectivity.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
