Encapsulate α-MnO2 nanofiber within graphene layer to tune surface electronic structure for efficient ozone decomposition

Abstract

Ozone is a major air pollutant, but its elimination is challenging. Here the authors encapsulate defective α-MnO2 nanofiber within ultrathin graphene shells to construct a hierarchical MnO2@graphene catalyst for ozone decomposition that possesses high activity and stability under humid conditions.
