Titanium foils for use in photoelectrochemical devices are treated with a HNO 3 ‐HF solution. After this treatment, the optical reflection characteristics of the Ti substrates are markedly increased in terms of not only reflectivity but also optimized wavelength. Furthermore, the “multiple beam interference” theory and optical analysis of surface morphologies clearly verify the origin of the optimized optical reflection properties.
