A wheel-shaped Zr-substituted phosphotungstate [{Zr(C₂O₄)₂}₃ (PO₄)(P₆W₃₉O₁₅₀)]³⁹⁻ with tunable proton conduction properties

Abstract

A novel wheel-shaped Zr-substituted phosphotungstate, [N(CH3)4]2K16Na10.5H10.5[{Zr(C2O4)2}3(PO4)(P6W39O150)]⋅45H2O was prepared, which exhibited a high proton conductivity of 1.18 × 10−2 S cm−1 at a higher temperature of 368 K.
