Synthesis and Photocatalytic Activity of Modified TiO2 Thin Films Prepared by Spray Pyrolysis

Solid State Phenomena 2017
Laura Rozenberga-Voska, Jānis Grabis

TiO2 and silver doped TiO2 thin films were prepared by spray pyrolysis technique and their photocatalytic activity were determined. Titanium(IV) isopropoxide solution or its mixture with silver nitrate were used as precursors. As-prepared at 300 °C films were X-ray amorphous. Calcination of the films at 500 °C for 5 – 6 hours allowed to obtain partially crystalline anatase films with uniform grain size in the range of 80 – 150 nm. Degradation degree of MB water solution by using TiO2 and TiO2/Ag photocatalysts under UV irradiation reached 60 and 70 % respectively.
