Extraction of polyoxotantalate by Mg–Fe layered double hydroxides: elucidation of sorption mechanisms

Abstract

Reaction of polyoxotantalate ions and MgFe Layered Double Hydroxide leads to magnesium polyoxotantalate precipitate.

Two resistance-switchable hybrid polyoxotantalates based on {Co2Ta12} clusters

“…[29][30][31] To date, only a tiny number of POTas have been discovered. [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] The reasons for the limited development of POTas include the chemical inertness of the tantalite species, the lack of soluble POTa precursors, the narrow reaction pH range (10)(11)(12), the low aqueous solubility of the common [Ta 6 O 19 ] 8− precursor, and the chemical incompatibility between POTas and other metal cations. It is worth noting that POTas have been shown to have significant application value in the fields of virology, photocatalysis, proton conductivity and base catalysis.…”
