The Effects of Annealing Temperatures and Dimethylformamide Doses on Porous TiO₂ Films

Crystals, 2022
In this study, we develop a facile and feasible synthetic technique for producing denser porous titanium dioxide (TiO2) films. The porous TiO2 films are effectively prepared using a sol–gel process with dimethylformamide (DMF).
