摘要：
In this report, ZnO hollow spheres were synthesized by an economic and environment-friendly bacterial template method. The hollow spheres resembled the morphology of the bacterial templates with multilayered porous shells. Their sensing properties were investigated with Co3O4 incorporation. The response of the spheres was enhanced from 8-11 to 38-49 to 100 ppm acetone with CO3O4 incorporation, and the response and recovery time were shortened from 10-12s and 61-795 to 1.2-1.9s and 27-48 s, respectively.
