Linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), and chronoamperometry in 1 M NaOH were used to evaluate the electrocatalytic activity for HER. By increasing the current density of electrodeposition up to 500 mA/cm², a columnar morphology was observed. The cyclic voltammetry test (CV) revealed that when the plating current density increases, C_dl has increased from 248 to 1310</span></span></span> <span style="font-size:12.0pt"><span style="line-height:115%"><span new="" roman="" style="font-family:" times="">&micro;F/cm² and the active surface area increases 5 times. The results showed that by modifying the coating morphology, the current density of the hydrogen evolution increased up to two times.</span></span></span></span></span></span><br> &nbsp; Electroplating, Coating, Hydrogen evolution reaction, Porous materials, Electrocatalyst 45 52 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-71-5&slc_lang=en&sid=1 Mohammad Derakhshani derakhshani.mo67@yahoo.com 1800319475328460019170 1800319475328460019170 No School of Metallurgy and Materials Engineering, Iran University of Science & Technology, Tehran, Iran Saeed rastegari rastegari@iust.ac.ir 1800319475328460019171 1800319475328460019171 Yes School of Metallurgy and Materials Engineering, Iran University of Science & Technology, Tehran, Iran Ali Ghaffarinejad Ghaffarinejad@iust.ac.ir 1800319475328460019172 1800319475328460019172 No Electroanalytical Chemistry Research Center, Iran University of Science and Technology, Tehran, Iran
