Photocatalytic properties of thermally annealed films of titanium butoxide

We show that titanium dioxide particles capable of Reactive oxygen species generation can be produced in titanium butoxide films by annealing them at 500$^\circ$C. Optimal conditions for the films deposition by a modified Langmuir–Blodgett technique were selected basing on the film uniformity examined by optical and electron microscopy. The photocatalytic activity of the annealed film was tested using RNO sensor bleaching.
