Enhanced OER kinetics with NiFeLa LDH electrocatalysts supported onto Ta-doped SnO2

Year: 2026

Type: article

Abstract: The direct synthesis of a series of NiFeLa-layered double hydroxides (LDH) supported on Ta-doped SnO2 (LDH@SnO2) was carried out at various loadings (15, 33 and 67 wt%). These materials provided enhanced oxygen evolution reaction (OER) kinetics in alkaline medium with Tafel slope values of 94.6 mV/dec and 130.6 mV/dec for 33LDH@SnO2 and 67LDH@SnO2, respectively. In addition, the 33LDH@SnO2 electrocatalytic material provided greater performance than the unsupported NiFeLa-LDH and was selected as anodic catalyst for full cell anion exchange membrane (AEM) electrolyser testing. The AEM water electrolysis cell provided a current density of 603 mA/cm2 with no performance decay after 24 h at 2.0V, thus indicatin its potential applicability in larger scale systems.
