“…TiO 2 thin film was prepared by spin coating method according to Schmuki and co-workers adapted methodology on the pre-treated metallic Ti plate. 23 A volume equal to 100 μl of 30% titanium isopropoxide solution in isopropanol was applied on the Ti plate while it was rotating at 300 rpm for 30 s under N 2 atmosphere. In the end, heat treatment was performed at 450 °C for 2 h in a muffle furnace.…”

Amorphous molybdenum sulfide (MoSx) is a promising material for hydrogen evolution reaction (HER) due to its nearly zero hydrogen adsorption free energy at the sulfur (S) edge-sites. To prepare more efficient MoSx-based electrocatalysts, new attempts are required to increase the exposure of the MoSx lateral size and, therefore, increase the S atom's contents. The majority of studies reported in the literature investigate MoSx over conductive substrates. However, MoSx can be electrodeposited over inexpensive and chemically stable platforms, such as semiconductors. This work presents the semiconductor substrate morphology effect for prepared sulfur-rich MoSx for electrochemical hydrogen evolution reaction. The electrodes are prepared by cyclic voltammetry with 25 cycles over TiO2 film and TiO2 nanotubes (TiO2NT) substrates. The MoSx deposit on TiO2NT presents an increase S atoms contents and exhibits excellent HER activity with a low overpotential of -93±7.5 mV to reach -10 mA cm-2 and a higher exchange current density equal to 91 µA cm-2, and a smaller Tafel slope of 43 mV dec-1.
