文摘

Nickel oxide films are directly grown onto a glass substrate via SILAR method. Films are polycrystalline and are made up of upright standing nanoplates. Chemoresistive performances toward ammonia, methanol, ethanol, liquefied petroleum gas and nitrogen dioxide gases are tested and reported. Good response of 72% to 5000 ppm LPG at 180 °C operating temperature is evidenced. Interaction between gas molecules and nickel oxide is proposed through potential barrier model.
