Perovskite-based electrocatalysts with compositional flexibility and tunable electronic structures have emerged as one of the promising non-noble metal candidates for oxygen evolution reaction (OER). Here, we propose a heterostructure comprising perovskite oxide (LaNiO3) nanorods iron hydroxide (FeOOH) nanosheets an effective electrochemical catalyst OER. The optimized 0.25Fe-LNO interesting 1D...
