A sensitive face: Polyhedral ZnSnO 3 microcrystals with controlled exposed facets are selectively synthesized in high yield by a convenient, repeatable, and low‐temperature process (see image). The polyhedral ZnSnO 3 particles have good gas‐sensing properties and show high sensitivity to H 2 S, HCHO, and C 2 H 5 OH, as well as good reproducibility and short response/recovery times. Different shapes of ZnSnO 3 polyhedra have unique gas sensitivity to the detected gases because of their different active facets.
