Abstract
Water-mediated surface self-assembly on PrBa<sub>0.8</sub>Ca<sub>0.2</sub>Co<sub>2</sub>O<sub>5+δ</sub> (PBCC) results in formation of BaCoO<sub>3−δ</sub> (BCO) nanoparticles to boost catalytic activity of oxygen reduction, as confirmed by <italic>in situ</italic> Raman spectroscopy at high temperatures (HT).
