Description
Summary:•A highly active rare earth Perovskite (ABO3) structures was successfully synthesized through an eco-friendly green synthesis method.•The synthesized gadolinium cobaltite (GdCoO3) nanorods and lanthanum cobaltite (LaCoO3) nanoplates shows excellent OER activity.•GdCoO3 shows the overpotential of 320 mV (vs. RHE) at the current density of 10 mA cm−2 and Tafel slope of 53.50 mV dec−1. Perovskite (ABO3) Structured gadolinium cobaltite (GdCoO3) nanorods and lanthanum cobaltite (LaCoO3) nanoplates are prepared via an eco-friendly green synthesis approach. The Perovskite-based nanostructures show an excellent oxygen evolution reaction (OER) with an overpotential of about 340 mV (LaCoO3) and 320 mV (GdCoO3) at a current density of 10 mA cm−2 in an alkaline medium. Based on the findings, GdCoO3 could be an excellent candidate as a high-performance electrocatalyst in OER application.
