Mo–V Keggin Structure Compound and Its Electrocatalytic Reduction Toward Bromate

AbstractIn this paper, the Mo-V Keggin compound 1, KNa 6 [VMo 12 O 40 ] 2 (OH)(H 2 O) 36 , had obtained. Single crystal X-ray analysis revealed that there is the nanometer-sized water cube, Na 6 (KOH)(H 2 O) 36 , in [VMo 12 O 40 ] 3− Keggin structure. The Na 6 (KOH)(H 2 O) 36 forms one cuboid house with long side of 22.456 A and short side of 11.228 A. The cation water cube acts as a “host” and the globular anion [VMo 12 O 40 ] 3− as “guest” which was captured. The cycle voltammetry study showed that above compound had excellent electrocatalytic activity toward the reduction of bromate. Thermogravimetric analysis was in agreement with the crystal data.Graphical AbstractIn this paper, the Mo-V Keggin compound 1, KNa 6 [VMo 12 O 40 ] 2 (OH)(H 2 O) 36 , had obtained.
