The purpose of this study was to correlate between photoelectrochemcial hydrogen production rate and electron transfer with various types of metal doped $TiO_2$ nanotubes as photoanodes. In order to fabricate light sensitized photoanode, CdS, $WO_3$, and Pt were doped by electrodeposition method. As the results of experiments, the electron transfer was favorable from higher position to lower position of conduction band (CB). In consequence, the higher hydrogen production rate was as follows, CdS/$TiO_2$ (100 $umol/hr-cm^2$) > $WO_3/TiO_2$ (20 $umol/hr-cm^2$) > Pt/$TiO_2$ (10 $umol/hr-cm^2$). The surface characterizations exhibited that crystal structure, morphological and electrical properties of various metal depoed $TiO_2$ nanotubes by the results of SEM, TEM, XPS, and photocurrent measurements.
