Abstract

Abstract: Oxygen vacancy engineering is a valid strategy to boost the oxygen reduction reaction (ORR) performance of nanostructured electrocatalysts. Current methods for generating surface oxygen vacancies (V_os) in nanostructured MnO₂ is mostly lab-scale, which cannot meet the requirement of large-scale production. Herein, we employed a mechanochemical method of ball milling to introduce surface V_os into the β-MnO₂ nanoparticles. The ball milling process generated abundant surface V_os, which significantly facilitated the adsorption and activation of O₂. Consequently, the ORR performance of ball-milled β-MnO₂ was markedly boosted by varying the ball milling time. As an air cathode catalyst for zinc-air battery (ZAB), the β-MnO₂ ball-milled for 4 h displayed a high specific capacity of 804 mA·h·g^-1 and excellent cycling over 500 h at 5 mA·cm^-2, which were superior than those of pristine β-MnO₂-based ZAB. Our work offers a feasible strategy to enhance electrocatalytic ORR performance of MnO₂, which shows significant potential for large-scale production of efficient ORR electrocatalysts.
