A new [SiMo12O40]4−-based metal organic framework: synthesis, structure, photo-/electro-catalytic and absorption properties
The water pollution problems caused by organic dyes, inorganic ions and other pollutants are becoming more and more serious, and the removal of pollutants from wastewater is still a challenge. A polyoxometalate-based metal organic framework [Pr4(bpdc)4(H2O)10]·SiMo12O40·3H2O (1) (H2bpdc = 2,2′-bipyridine-6,6′-dicarboxylic acid) was synthesized for multi-functional treatment of pollutants in water. Structural analysis revealed that Keggin-type polyanions are sandwiched between adjacent lanthanide-organic layers. Electrochemical and dye removal experiments showed that compound 1 can not only reduce NO2− and BrO3− pollutants in water by electrocatalytic oxidation, but also photocatalytically degrade and adsorb cationic organic dye pollutants in water, and even adsorb cationic organic dyes from mixed dyes solution. It has been proved that compound 1 is a multifunctional water treatment agent.
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.
