Herein, we describe a facile surfactant-free method to prepare the ZnO–Ag hybrids at room temperature for improving gas-sensing performance toward ethanol. Characterizations indicate that Ag nanoparticles are well deposited on surface of ZnO nanorods. It is interesting note introduction only 1 wt % in leads impressive enhancement properties ZnO. Notably, can offer gas response value 884.7 1000 ppm ethanol (approximately 12.6 times higher than pure nanorods). Meanwhile, exhibit excellent stability with ±5% fluctuation over period 480 cycles. Moreover, above-mentioned also good selectivity (about 4.7–52.9 greater other tested vapors). The high sensitivity, and presented by make it potential material developing an sensor
