| Abstract: | Hollow ZnO spheres were prepared in solution phase using newly made carbon microspheres as the templates.ZnO sensors were fabricated from hollow ZnO spheres and their gas sensing properties were investigated.It was found that hollow ZnO spheres gas sensors had good response to ethanol,acetone,H2S and(C2H5)3N.Remarkably,hollow ZnO spheres gas sensor exhibited the best performance,characterized by high response,and very short response time to dilute(C2H5)3N at 175℃ and ethanol at 400℃. |
