Microwave assisted hydrothermal synthesis of single crystalline ZnO nanorods for gas sensor application

► ZnO nanorods are synthesized by microwave assisted hydrothermal method in one hour. ► These ZnO nanorods are single crystalline in nature. ► These ZnO nanorods are applied for CO, ethanol and acetaldehyde gas sensor. ► These ZnO nanorods show high response for ethanol at low temperature. ► These ZnO nanorods can be selectively used as ethanol gas sensor.
