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：
Transition Metal Chemistry is an international journal designed to deal with all aspects of the subject embodied in the title: the preparation of transition metal-based molecular compounds of all kinds (including complexes of the Group 12 elements), their structural, physical, kinetic, catalytic and biological properties, their use in chemical synthesis as well as their application in the widest context, their role in naturally occurring systems etc.
Manuscripts submitted to the journal should be of broad appeal to the readership and for this reason, papers which are confined to more specialised studies such as the measurement of solution phase equilibria or thermal decomposition studies, or papers which include extensive material on f-block elements, or papers dealing with non-molecular materials, will not normally be considered for publication. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures.
