Humidity sensor based on mesoporous Al-doped NiO ultralong nanowires with enhanced ethanol sensing performance

Mesoporous Al-doped NiO ultralong nanowires with better uniformity, dispersity and well-defined morphologies were synthesized by a simple surfactant based hydrothermal treatment of aqueous solution of Al(NO3)3, NiCl2 and NaC2O4 in the presence of ethylene glycol and polyethylene glycol through continuous open air heating at 500 °C. The sensing performances of the gas sensor’s based on bare and Al-doped NiO nanowires had been investigated towards...
