Laser-Treated MXene as an Electrochemical Agent to Boost Properties of Semitransparent Photoelectrode Based on Titania Nanotubes

“…The improvement of the electrochemical activity of TiO 2 /Ti 3 C 2 T x material by the −OH surface termination groups is explained as follows: The higher content of hydrophilic −OH groups increases the ability of the aqueous electrolyte to infiltrate through the porous active material, which facilitates the ion transport across the tubular oxide layer during the electrochemical process. As a result, more active sites are exposed for the electrolyte penetration. , In that way more Na + cations can be intercalated as well into the interlayer spacing of MXenes, thereby increasing the current density. The reduction observed at the cathodic limit can be associated with the reduction of different titanium states: Ti 4+ + e – → Ti 3+ and Ti 3+ + e – → Ti 2+ , detected by XPS measurements, with concomitant hydrogen evolution from water in the electrolyte.…”
