Abstract

In this paper, we present an approach for the precisely controlled phase transformation of MnOin order to synthesise different compositions of α-/β-MnOmaterials, by adding a trace amount of Zn(acac)as the phase transformation-inducing agent in a hydrothermal reaction. The single-atomic dispersion of Zn might reduce the barrier of phase transformation of δ-MnOto β-MnO. The ratio of the Zn species present in the single-atomic dispersions and nanoclusters might dominate the generation of α-MnOand β-MnO. The results of the oxygen reduction reactions indicate that the MnOmaterials have potential applications as promising catalysts in electrochemical catalysis.
