    Electrochemical Behavior of Single Pt atoms dispersed on Cu/Ni Electrode in Alkaline Environment
    (2023) DÖNER, ALİ; Toprak Döşlü, Serap
    It is important the development of cost-effective Pt based electrocatalyst for industrial water splitting. In this study, to prepare cost-efficient Pt-based electrocatalyst for hydrogen evolution, Cu electrode is deposited with nickel (Cu/Ni) and this surface is modified with single atom dispersion of Pt by electrodeposition method (Cu/Ni-Pt). Hydrogen evolution and corrosion behaviours of prepared electrode (Cu/Ni-Pt) are examined in 1.0 M KOH solution using cyclic voltammetry (CV), cathodic current-potential curves, electrochemical impedance spectroscopy (EIS) and anodic current-potential curves. Moreover, electrocatalytic activity of Cu/Ni-Pt is also compared with Cu/Ni-Pd. The resultant Pt-based electrocatalyst with single atom dispersion has remarkably boosted hydrogen evolution acitivity of Cu/Ni as well as showing high corrosion performance after long-term immersion times. We emphasize the investigation of Pt-based single atom-containing electrocatalysts on the HER activity.
