Superprotonic Conduction in Donor Co-Doped Perovskites.

ABSTRACT: Donor doping of oxygen-deficient BaScO_2.5 is an unexplored strategy for achieving high proton conductivity at intermediate temperatures of 200-400 °C. In this work, a new series of BaSc_{1- x - y}Mo_xW_yO_{3- δ} compounds was prepared via Mo/W donor co-doping where x is the Mo content, y is the W content, and δ is the amount of oxygen vacancies. The present work reports the enhancement of proton conductivity by the Mo/W donor co-doping of BaScO_2.5. BaSc_0.8Mo_0.1W_0.1O_2.8 exhibits exceptional proton conductivity-0.10 S cm^{- 1} at 315 °C and 0.01 S cm^{- 1} at 193 °C-alongside outstanding chemical stability in C
