NO sensing characteristics of ZnO nanorod prepared by ultrasound radiation method

Nitric oxide gas sensing at room temperature by functionalized single zinc oxide nanowire

“…Moreover, relatively large surface defects and favorable gas adsorption/desorption parameters [10,11], give ZNW edge over other nanowires and nanotubes for NO gas detection. There have been many reports on ZNW based gas sensors for the detection of ethanol, CO, NH 3 , H 2 , O 2 , NO, H 2 S and NO 2 [9,[12][13][14][15][16][17]. However, these sensors need to be operated at high temperature to achieve improved gas-semiconductor surface reaction and high signal to noise ratio [9,13].…”

In their study, Fan and Lu [18] have demonstrated a strategy for NO 2 gas sensing at room temperature by gate refreshable ZNW field effect transistors.…”

“…Moreover, relatively large surface defects and favorable gas adsorption/desorption parameters [148,149], give ZNW edge over other nanowires and nanotubes for NO gas detection. There have been many reports on ZNW based gas sensors for the detection of ethanol, CO, NH 3 , H 2 , O 2 , NO, H 2 S and NO 2 [24,31,35,147,[150][151][152]. However, these sensors need to be operated at high temperature to achieve improved gas-semiconductor surface reaction and high signal to noise ratio [147,150] Metal particles are well-known as effective catalysts, due to their ability to control the redox reactions of the gas molecule at the sensor surface [156].…”

At nanoscale, metal particles show superior catalytic properties due to their high surface to volume ratio and chemical potential [157].…”
