Intercalating potassium-aqua complex cation into α-MoO3 layer without reducing molybdenum: a potential storage system
Abstract
We have demonstarted a green aqueous synthesis of rod-shaped MoO3 material, [MoVI3O9{K(H2O)4}(CH3COO)]∙H2O (2) intercalating potassium-aqua-complex acetate into its lamellar space, simply by ion-exchange of Co(II)-aqua-complex in compound [MoVI4O12(CH3COO)2{CoII(H2O)6}]∙2H2O (1) by {K(H2O)4}+ in an aqueous solution of 1 and KCl. Compound 2 acts as potential storage system of alkali metal ions.
