By performing electrochemical anodization on Ti29Nb13Ta4.6Zr alloys, quaternary Ti-Nb-Ta-Zr-O (TNTZO) mixed-oxide nanotube arrays with controllable geometric features were prepared. Compared with pristine TiO2, the TNTZO photoanodes exhibited noticeably enhanced photoactivity toward solar water splitting. The analytic results of time-resolved PL, EIS, and Voc decay measurements manifest that the superior photoactivity of TNTZO originated from the introduction of Nd, Ta, and Zr elements, which enhanced the amount of accessible charge carriers, modified the electronic structure, and improved the hole-transfer kinetics for expediting water splitting.
