Abstract
The present disclosure provides a gas sensor comprising a gas sensing layer fabricated based on a solution-processed, template-free synthesis method that achieves controllable ZnO nanostructured morphologies. The method is based on promotion and suppression of growth at specific crystallographic dimensions by tuning the polarity of the solvent. The gas sensing layer with the ZnO nanostructures exhibits high response, excellent selectivity and rapid recovery time.
