ΠεριγραφήThe authors would like to acknowledge the HELLAS-CH national infrastructure (MIS 5002735) implemented under “Action for Strengthening Research and Innovation Infrastructures,” funded by the Operational Program” Competitiveness, Entrepreneurship and Innovation” (NSRF 2014-2020) and co-financed by Greece and the European Union (European Regional Development Fund).en
ΠερίληψηIn this study, a two-step electrode fabrication process is used to enlarge the electrocatalytic area of the electrodes and improve the hydrogen evolution reaction. Nickel electrodes were laser-nanostructured, and afterward, they were galvanostatically electrodeposited, a novel approach for electrodes used for HER. SEM and EDX analysis were performed. The electrochemical evaluation provided enhanced values of overpotential (η10 = 108 mV), Tafel slope (b = −121 mV dec−1) and double layer capacitance (1945 μF cm−2) compared to the literature. The stability of the electrodes was tested by its overpotential (|η100|=264 mV) in a current density of 100 mA cm−2.el
