Abstract

The monodisperse triclinic WO₃ nanoparticles with exposed (001), (100) and (010) facets have been successfully synthesized via a simple hydrothermal route with the assistance of tartaric acid. The percentage of exposed facets can be regulated by changing the amount of tartaric acid. On the bases of the structural analysis and gas sensing results, we indicated that the monodisperse WO₃ nanoparticles with exposed more percentage of (010) facets exhibit better gas sensing to 1-butylamine.
