Efficient oxygen evolution activity of CoFe-PBA heterojunctions using a bimetallic probe (Mo/Cu) at room temperature: construction of multilayered activated structures and cationic vacancies

Multilayer active heterojunctions and Co ionic vacancies (V Co ) were successfully constructed by bimetallic probes (Mo/Cu) in CoFe-PBA precursors. This makes it a new strategy for doping various types of isotropic metals at room temperature.
