Yttrium-doped barium zirconate (BZY) has emerged as an attractive candidate for application a proton (H+)-conducting solid electrolyte due to its high ionic conductivity and excellent chemical stability. In this study, the conductivities of BaZr(1?x)YxO3?? (BZY, x = 0, 0.037, 0.074, 0.148, 0.22) with different carriers were studied based on density functional theory (DFT) experiments. The resul...

We developed an Fe2O3/BZY (yttrium-doped barium zirconate)–RuO2 (Fe/BZY–RuO2) cathode catalyst, which was applied to the electrochemical synthesis of NH3 using a proton-conducting electrolyte, CsH2PO4/SiP2O7, at 220 °C and ambient pressure.
