摘要: The perovskite SrNb0.1 Co0.7 Fe0.2 O3-δ (SNCF) is a promising OER electrocatalyst for the oxygen evolution reaction (OER), with remarkable activity and stability in alkaline solutions. This catalyst exhibits higher intrinsic activity, smaller Tafel slope better than state-of-the-art precious-metal IrO2 well-known BSCF perovskite. mass are further improved by ball milling. Several factors including optimized eg orbital filling, good ionic charge transfer abilities, as well high OH(-) adsorption O2 desorption capabilities possibly contribute to excellent activity.
