Study of the Photocatalytic Properties of Ni-Doped Nanotubular Titanium Oxide

Nanotubular titanium oxide is widely known as a prospective semiconductor photocatalyst for the process of water splitting. Its photoelectrochemical (PEC) efficiency can be improved by doping with 3d metal. In this work, synthesis nanotubular (NTO) was carried out anodizing substrates using two techniques. First, Ni-doped TiO2 obtained immersion in Ni salt solution; second, an ethylene glycol-based fluoride electrolyte containing Ni2+ ions solution used. The samples were analyzed SEM, XRD, and methods. produced NTO exhibited photocatalytic activity twice high that nondoped NTO. Additionally, it found technique initiated shift incident photon to converted electron (IPCE) spectra visible part spectrum.
