Structural Characterization of Carbon‐Doped and Carbon‐Coated TiO2 Core–Shell Nanoparticles
Advanced Materials Interfaces, EarlyView.Carbon‐doped TiO2${\rm TiO}_2$ nanoparticles were produced by heating pristine TiO2${\rm TiO}_2$ in acetylene/nitrogen gas, forming a thin graphene‐like shell around each particle. The analysis of the particles indicate that some carbon enters the TiO2${\rm TiO}_2$ structure at interstitial sites.
