| Outline of Final Research Achievements |
Volatile Organic Compounds (VOC) gas sensor using ZnO with hierarchical structures was investigated.
ZnO particles were synthesized solvothermally from the solution of zinc acetate and hexamethylenetetramine in ethylene glycol and water. ZnO spherical particles composed of pyramid-shaped crystallites, which were radially aligned along the c-axis, and the broken particles were obtained. We evaluated their gas sensing properties to ethanol gas and demonstrated that the collapse of the spherical particles led to a high sensitivity.
