Bor Katkılı TiO2 Nanotüp Fotokatalizörlerinin Üretimi ve Karakterizasyonu

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
