Abstract
In this thesis, TiO2 nanotube arrays (TND) were grown on
titanium foil using anodic oxidation (anodization) method. To understand the
effect of water in the electrolyte, different amounts of water were added to
the TiO2 nanotube arrays. The crystal structure and surface
morphology of the obtained TiO2 nanotube arrays were examined by XRD
and SEM techniques. Photo-electrocatalytic activities and electrochemical
impedance spectra (EIS) of TNDs grown in electrolytes containing different
water additives were investigated. As the amount of water in the electrolyte
increased, the nanotube morphology deteriorated, but the crystal structure
improved. Furthermore, as the water additive increased, TNDs showed better
photo-electrocatalytic performance. In direct proportion to this, it was
observed that the load transfer resistance on the surface of the TND decreased
as the water contribution increased.

Abstract
Bu tez çalışmasında, anodik oksidasyon (anodizasyon) yöntemi kullanılarak,
TiO2 nanotüp dizileri (TND) titanyum folyo üzerine büyütülmüştür.
TiO2 nanotüp dizilerine, elektrolit içindeki suyun etkisini anlamak
için, çözeltilere farklı miktarlarda su eklenmiştir. Elde edilen TiO2
nanotüp dizilerinin kristal yapısı ve yüzey morfolojisi XRD ve SEM teknikleri
ile incelenmiştir. Farklı su katkıları içeren elektrolitlerde büyütülen,
TND’lerin foto-elektrokatalitik aktiviteleri ve elektrokimyasal empedans
spektrumları (EIS) incelenmiştir. Elektrolit içerisindeki su miktarı arttıkça
nanotüp morfolojisi bozulmuş fakat kristal yapısı iyileşme gözlemlenmiştir.
Ayrıca, su katkısı artıkça, TND’ler daha iyi foto-elektrokatalitik performans
göstermiştir. Bununla doğru orantılı olarak, su katkısı arttıkça TND’lerin
yüzeyindeki yük transfer direncinin azaldığı görülmüştür.
