Bu çalışmada, sol-gel yöntemiyle hazırlanmış olan
titanium dioksit esaslı katalizörlere praseodymium (Pr) katkılanmasının ve
kalsinasyon sıcaklığının metilen mavisinin fotokatalitik bozunma
reaksiyonundaki etkileri araştırılmıştır. Titanyum dioksitin %1 oranında Pr
katkılanması anataz kristallerinin rutil yapısına dönüşmesini engelleyerek daha
kararlı bir anataz yapısının oluşmasını sağlamakta, yüzey alanını ve
fotokatalizörün ışık absorpsiyon kapasitesini artırmaktadır [1]. Metilen
mavisinin fotokatalitik bozunma reaksiyonunda Pr katkılanmasının yanısıra katalizörün
kalsinasyon sıcaklığının etkisi hem toz hem ince film katalizorler uzerinde etüd
edilmiştir. Deneysel sonuçlar, 600 °C’da kalsine edilen katalizörlerin 500 °C’da
kalsine edilen numunelere göre daha yüksek fotokatalitik aktiviteye sahip
olduklarını göstermiştir. Ayrica, Pr katkılanması toz halindeki TiO₂
katalizörlerin fotokatalitik performansını iyileştirmiş olup metilen mavisinin
tam dönüşmesini sağlamıştır.  Metilen
mavisi moleküllerinin dimerizasyonu da bozunma reaksiyon hızını etkilemekte olup
Pr katkilanmis numunelerde dimerlerin monomere dönüşümünün daha hızlı
gercekleştigi görülmüşür.
