The paper aims to investigate the Ni/TiO2 nanocomposite layers with different concentrations of TiO2 nanoparticles (mean diameter size of 10 nm) for electrocatalytic activity of hydrogen evolution reaction in 0.5 M NaOH solution by cathodic linear polarization measurements (LP) and electrochemical impedance spectroscopy (EIS) performed at cathodic potentials. Knowing that nickel and nickel alloys have good electrocatalytic activity for the hydrogen evolution reaction (HER) and good resistance to corrosion in alkaline environment, the research work compares the electrocatalytic activity of Ni/TiO2 nanocomposite layers with pure nickel coating. The results show an improving of electrocatalytic activity by adding nano dispersed TiO2 particles into nickel matrix..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
