Abstract: The electrocatalytic oxidation of aliphatic alcohols in alkaline solutions at a nickel-based chemically modified glassy carbon electrode (Ni-CME) was investigated. The electrode was characterized by voltammetry and flow injection and applied for amperometric detection of mono- and polyhydric alcohols separated by liquid chromatography. A mechanistic electrooxidation model is proposed that involves a Langmuir-type adsorption process on different sites: NiO and NiOOH for polyhydric and monohydridic compounds, respectively. The process is followed by a hydrogen abstraction from the carbon α to the OH group through a radical pathway in the rate-determining step
