Abstract
Three polyoxometalate-based metal–organic complexes with the ability to treat pollutants in water were obtained under hydrothermal conditions using two flexible bis(triazole) organic ligands, [Cu(bte)2(H2O)]2[SiMo12O40]·2H2O (1), [Cu(btb)2]2[SiMo12O40]·H2O (2) and [Cu(btb)2(H2O)]2[SiMo12O40] (3) (bte = 1,2-bis(1,2,4-triazol-1-yl)ethane; btb = 1,4-bis(1,2,4-triazol-1-yl)butane). In compound 1, Cu2+ ions are linked by bte into a two-dimensional network layer with [SiMo12O40]4- anions filled between the layers as guest molecules. In compound 2, [SiMo12O40]4- anions act as four-connected ligands to coordinate with Cu2+ and fill in the pores of the three-dimensional framework constructed by Cu2+ and btb. In compound 3, [SiMo12O40]4- anions act as guest molecules to fill the channels of the two-dimensional layer formed by Cu2+ and btb. The electrochemical characteristics were studied, such as cyclic voltammetry, electrocatalytic reduction and oxidation of water contaminants, and current sensing of BrO3-. The photocatalytic degradation of organic dye pollutant MB (methylene blue) performance was also investigated under visible light conditions.
期刊介绍:
Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews.
Topics covered include:
• chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies;
• synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs);
• reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models;
• applications of inorganic compounds, metallodrugs and molecule-based materials.
Papers composed primarily of structural reports will typically not be considered for publication.
