Synthesis of trapezohedral indium oxide nanoparticles with high-index {211} facets and high gas sensing activity.
Nanocrystals with high-index facets usually exhibit higher catalytic activities than those with only low-index facets. Trapezohedron-shaped (TS) In2O3 particles with exposed high-index {211} facets were successfully synthesized in an oleic acid (OA) and trioctylamine (TOA) system. It has been demonstrated that the gas sensing activity of TS In2O3 particles with exposed high-index {211} facets is higher than that of octahedron-shaped In2O3 particles with exposed low-index {111} facets.
