Abstract

Selective exposure of high-energy {221} facets with many surface dangling bonds, (111) terraces, and (110) steps (bottom picture) at the surface of octahedral SnO₂ nanoparticles (top) through a simple hydrothermal synthesis route gives them enhanced gas-sensing performance over particles with other shapes, whereby the sensing activity is proportional to the fraction of {221} facets among the exposed surfaces.
