Enhanced electrochemical hydrogen storage performance of lanthanum zirconium oxide ceramic microstructures synthesized by a simple approach

Two rare-earth zirconate oxides RE2Zr2O7 (RE = La and Nd) with pyrochlore structures were fabricated, employing a simple and modified solid-state route. After confirmation of their microstructure, physicochemical features, and morphologies, the fabricated pyrochlores were applied for electrochemical hydrogen storage, and their capacity was compared in an alkaline medium. The La2Zr2O7 microstructure exhibited an enhanced electrochemical hydrogen …
