To　provide　clean　energies,　great　efforts　have　been　contributed　to　hydrogen　production　via　photocatalytic　water　splitting　over　the　past　decades.　Among　many　potential　materials,　TiO2　nanotube　array　has　been　considered　as　one　of　the　most　attractive　photoanodes　due　to　its　advantages,　such　as　low　cost,　non-toxicity　and　chemical　stability.　It　has　been　discovered　that　TiO2　nanotube　arrays　(TNTs)＇　photocatalytic　performance　was　dictated　by　their　morphologies,　which　is　mainly　controlled　by　the　outer　voltage.　In　order　to　further　understand　the　effect　of　TNTs＇　morphologies　on　their　photocatalytic　capability,　TNTs　with　different　structures　had　been　fabricated　under　different　voltage　(10,　20,　30,　40　and　50　V).　The　obtained　TNTs＇　morphologies　and　phase　were　characterized　by　scanning　electron　microscope　(SEM),　transmission　electron　microscope　(TEM)　and　X-ray　diffraction　analyzer　(XRD).　The　photocatalytic　properties　of　TNTs　were　investigated　in　aqueous　solution　under　xenon　lamp　irradiation.　It　was　identified　that　the　highest　hydrogen　production　of　the　sample　synthesized　at　the　voltage　of　30　V　was　1979.8　mu　mol/h　during　the　first　cycle.
