[Display omitted] •The crystal phase adjustment was used to design TiO2 with three different phases.•The rutile TiO2 based sensor displayed the best acetone sensing properties.•The rutile TiO2 possessed relatively narrow band gap and more oxygen vacancies. Gas sensors have become increasingly signif...
