Abstract
By using one-step anodizing, W–Mn–TiO2 nanotubes (W–Mn–TNTs) were synthesized in different ratios of two metals. The surface morphology and structure of the W–Mn–TNTs samples were characterized by FE-SEM, XRD, EDAX-mapping, and the optical features of the samples were studied by UV–Vis. The photoelectrochemical behavior of the samples was investigated by linear sweep voltammetry, chronoamperometry, and open-circuit potential. The obtained results showed the new doped synthesized samples have better photoelectrochemical properties compared to the bare TiO2. The K2 sample (synthesized in anodizing solution containing 9 mM Na2O4W and 3 mM KMnO4) showing the best result compared to the others, was examined in the presence of different alcohols as sacrificial agents in photoelectrochemical cells water splitting. The glycerol demonstrated a better result than the rest samples.
