Precursor-mediated synthesis and sensing properties of wurtzite ZnO microspheres composed of radially aligned porous nanorods.

Wurtzite ZnO microspheres composed of radially aligned porous nanorods are prepared via a simple thermal treatment of a "pre-synthesized" zinc monoglycerolate precursor. The as-prepared hierarchical nanomaterial can serve as a highly sensitive sensing material for ethanol detection.
