Titanium oxide nano tubes (TiOx) were prepared by the electrochemical anodizing method
from at different process time and different potential in 0.1 M HF solution. Their
morphologies were determined with surface photographs and scanning electron microscopy (SEM) images. Ni nano particles were deposited in conductive TiOx nano tubes arrays
via pulsed electrodeposition method. Their catalytic activity towards the hydrogen
evolution reaction (HER) was assessed by recording cyclic voltammetry technique, cathodic
currentepotential curves, hydrogen gas volumes and electrochemical impedance spectroscopy techniques. The highest HER activity thought the studied is observed on the
TiOx(30)-Ni.This study has been financially supported by The Scientific
