Synthesize of Mesoporous ZnO Thin Films and Gas Sensing Property

Article Preview

Abstract:

In this work, ordered mesoporous ZnO thin films was synthesized and gas sensor properties were introduced. Mesoporous ZnO thin films were successfully formed by sol-gel process. In ZnO structure, complex agent (MEA) was used for the hydration and condensation reaction. According to the change of MEA concentration, porosity and pore arrangement, specific surface area could be changed. As complex agent concentration decreased, pore ordering was increased and gas sensitivity has the high value (8.01).
