High efficiency electrocatalyst of LaCr(0.5)Fe(0.5)O(3) nanoparticles on oxygen-evolution reaction

Due to the multistep proton-coupled electron transfer, it remains a huge challenge to accelerate the kinetics of oxygen evolution reaction (OER). Here, we demonstrate that perovskite-type LaCr(0.5)Fe(0.5)O(3) nanoparticles can be used as highly active and stable OER electrocatalysts, where it shows...

description Due to the multistep proton-coupled electron transfer, it remains a huge challenge to accelerate the kinetics of oxygen evolution reaction (OER). Here, we demonstrate that perovskite-type LaCr(0.5)Fe(0.5)O(3) nanoparticles can be used as highly active and stable OER electrocatalysts, where it shows a low overpotential of 390 mV at 10 mA/cm(2), a small Tafel slope of 114.4 mV/dec and excellent stability with slight current decrease after 20 h, superior than that of their individual counterparts (LaFeO(3) and LaCrO(3)). This finding confirms that the present hybrid material would be an effective means to electrocatalyst for catalyzing OER.
