Precise-Control Synthesis of α-/β-MnO2 Materials by Adding Zn(acac)2 as a Phase Transformation-Inducing Agent

Abstract

In this paper, we present an approach for the precise-control phase transformation of MnO2 to synthesis of different compositions of α-/β-MnO2 materials by adding a trace Zn(acac)2 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-MnO2 to β-MnO2. The ratio of Zn species present in single-atomic dispersion and nanoclusters might dominated the generations of α-MnO2 and β-MnO2. The oxygen reduction reaction results indicate that the MnO2 materials have potential applications values as promising catalysts in electrochemical catalysis.
