•1D and 3D nanostructures were obtained by oxidation processes of titanium foils.•The influence of methods of the oxidation on the morphology of TiO2 were studied.•Correlation between parameters of the semiconductor-electrolyte interface and photocurrent was established.•3D nanomaterials are promising candidate for photoanode in PEC.
TiO2 nanostructures were grown by oxidizing titanium foil. 1D nanomaterials were obtained via anodization in an electrolyte containing 1 wt% NH4F, ethylene glycol and 2 wt% H2O. Flower-like titanium dioxide (3D) was fabricated using chemical oxidation in a 30% H2O2 solution at moderate temperature. XRD analysis revealed a mixture of anatase and a smaller amount of rutile TiO2. The shape of photocurrent-voltage characteristics recorded in a photoelectrochemical cell (PEC) was found to be affected by the type of nanostructure. It was shown that 3D interconnected architecture improved photoelectrochemical performance.
