Square Wave Voltammetric Detection of Nitrite on Platinum Electrode Modified with Moringa oleifera Mediated Biosynthesized Nickel Nanoparticles
Solomon A. Mamuru*, Nelson Saki, Dahiru M. Bello, Moorey B. Dalen


In this study nickel chloride was reduced to its nanoform through a one-step synthesis protocol using the leaves extract of Moringa oleifera. Microscopic and spectroscopic techniques such as UV-vis., FTIR and SEM were used to confirm the formation of nickel nanoparticles. Electrochemical characterization using cyclic voltammetry and square wave voltammetry further reveals the electrochemical activity of synthesised nickel nanoparticles; as preliminary study on nitrite electro-oxidation shows that nickel nanoparticles can catalyse this process better than some other nanoparticles.
