DOI: 10.1016/j.jpowsour.2020.228748
Abstract: Abstract Tailoring the surface structure of Earth-abundant perovskite oxides can provide cost-effective, high-efficient, and durable electrocatalysts for oxygen evolution reaction (OER). However, the structural origin leading to high OER performance of perovskite is not fully… read more here.
