TiO₂ nanotüp fotokatalizörleri
titanyum levhaların anodizasyonu ile sentezlenmiştir. Sentezlenmiş olan TiO₂
nanotüp fotokatalizörlerinin bor katkılaması, borik asit içeren elektrolit
içerisinde elektrokimyasal muamele ile gerçekleştirilmiştir.  Elde edilen saf ve katkılı fotokatalizörlerin
karakterizasyonu SEM-EDS, XRD ve kronoamperometri ölçümleri ile yapılmıştır. Üretilen
fotokatalizörlerin fotokatalitik aktiviteleri Orange G boyası kullanılarak gerçekleştirilmiş
ve B katkılı TiO₂ nanotüp fotokatalizörünün, katkısız TiO₂
fotokatalizörüne göre % 24,75 oranında daha fazla giderim gösterdiği
belirlenmiştir. 

Anahtar Kelimeler

TiO2 nanotüp, fotokatalizör, bor katıkılı TiO2, fotokatalitik aktivite
