Ultrasensitive and selective 4-aminophenol chemical sensor development based on nickel oxide nanoparticles decorated carbon nanotube nanocomposites for green environment

Carbon nanotubes were decorated with nickel oxide nanoparticles to make nanocomposites (NiO·CNT NCs) by facile wet-chemical process in alkaline medium. Then NCs were deposited onto a flat glassy carbon electrode (GCE) with the help of conducting coating binders (5% Nafion) to give a selective, reproducible, stable, and sensitive 4-aminophenol (4-AP) chemical sensor development with NiO·CNT NCs/GCE assembly by reliable I-V method at room conditions.68
