Nickel oxide Nanoparticles/Carbon Nanotubes Nanocomposite for Non‐enzymatic Determination of Hydrogen Peroxide

Electroanalysis, Volume 35, Issue 2, February 2023., 2023
Abstract In this work, nickel oxide nanoparticles‐modified multi‐walled carbon nanotubes (CNTs) were prepared and used for H2O2 sensing application. Firstly, ex situ NiO nanoparticles (NPs) were prepared and further used to decorate polyethylenimine (PEI)‐modified carboxylated CNTs. The obtained nanocomposite and its precursors were identified by using
