Abstract

Yolk–shell MoO3 microspheres are prepared by a two-step process in which molybdenum oxide–carbon (MoOx–C) composite microspheres are first obtained by spray pyrolysis, followed by combustion at 400 °C in air. The yolk–shell microspheres exhibit excellent electrochemical properties and structural stability.
