Controllable La Deficiency Engineering within Perovskite Oxides for Enhanced Overall Water Splitting.

ABSTRACT: Recently, perovskite (ABO₃) nanomaterials have been widely explored as a class of versatile electrocatalysts for oxygen evolution reactions (OER) due to their remarkable compositional flexibility and structural tunability, but their poor electrical conductivity hinders hydrogen evolution reaction (HER) activity and further limits the large-scale application of perovskite oxide in overall water splitting (OWS). In this study, hollow-nanotube-structure La_xCo_0.4Fe_0.6O_3-δ (x = 1.0, 0.9, and 0.8) perovskites with superior HER/OER activity were synthesized on nickel-iron alloy foam (denoted La_xCoFe/NFF) using hydrothermal with a subsequent calcination strategy. Among them, La_0.9CoFe/NFF not only exhibited extraordinary
