Electrical conduction and NO2 gas sensing properties of ZnO nanorods

A study on the sensing of NO2 and O2 utilizing ZnO films grown by aerosol spray pyrolysis

“…Recently, Sahin et al [62] reported UV activated room temperature NO 2 sensors based on ZnO nanorods thin film sensors and demonstrated that UV light source-assisted sensors can be used to improve gas sensing properties, response, and recovery times at ppm level at low temperatures. On the other hand, Coban et al [63] analysed O 2 gas response behaviour of electrochemically deposited ZnO thin films to obtain better sensing characteristics without using any dopants and their gas responses were found to be linearly increased with operating temperature.…”

Room temperature NO2 sensing performance of free-standing mesh-structure vanadium dioxide nanorods by a chemical vapour deposition method

“…Nitrogen dioxide (NO 2 ) gas is the main cause of acid rain and photochemical smog, thus it is of great significance to research and develop NO 2 gas sensor [1,2]. Numerous attempts have been made to use metal oxide semiconductors as sensitive functional material in gas sensors, such as WO 3 , ZnO, SnO 2 and Cu 2 O [3][4][5][6][7][8][9][10]. Among extensive researches for nanostructure sensitive materials, WO 3 and SnO 2 are two of the most interesting materials in detecting NO 2 .…”
