Abstract
A highly stable layered zirconium phosphate (NH4)2[ZrF2(HPO4)2] (ZrP-1) was synthesized by ionothermal method and contains an extremely dense two dimensional hydrogen bond network that is thermally stable up to 573 K, leading to combined ultrahigh water-assisted proton conductivities of 1.45 × 10-2S cm-1at 363 K/95% RH and sustainable anhydrous proton conductivity of 1.1 × 10-5S cm-1 at 503K.
