Abstract

In order to fully utilize solar light, highly ordered Fe-N co-doped TiO2 nanotube array films (NAFs) were fabricated by electrochemical anode oxidation method combined with wet chemical method. The morphology, structure and composition of the as-prepared NAFs were characterized by XRD, SEM and EDX. The concentration of Fe and N on photoelectrochemical property of the TiO2 NAFs was investigated. The results showed that Fe and N atoms were successfully introduced into the NAFs and enhanced their photoelectrochemical property obviously under solar light. The optimum photoconversion efficiency of 4.83% from light energy to chemistry energy was obtained by preparation in 0.10M/L Fe(NO3)3..
