Year: 2025

Type: article

Abstract: An example of an inorganic–organic hybrid compound {[Ag4(SiW12O40)(HBTA)8][Ag4(SiW12O40)(HBTA)8(H2O)]}n·(1) modified by the Keggin-type [SiW12O40]4− polyoxoanion was synthesized hydrothermally, which was determined by single crystal X-ray diffraction. Two 1-dimensional (1D) chains are present in 1: chain a is connected by Ag···Ag interactions and chain b is connected by π···π stacking. Finally, they were extended into 2D and 3D supramolecular structures by hydrogen bonding. The photodegradation of methylene blue (MB) was investigated under visible light irradiation, and the degradation rate reached 99.4% within 200 min. In addition, 1 catalyzes the reduction of sodium nitrite and can be used as a potential electrocatalytic material.
