The Influence of pH on the Nitrogen-doped TiO2 Structure and Its Photocatalytic Activity on Methylene Blue Degradation

The mesoporous nitrogen-doped titania (N-doped TiO2) has been synthesized through sol-gel method by refluxing the precursor mixture, continued by hydrolysis process, and then followed by annealing in air at the desired temperature. The pH of precursor mixture solution before hydrolysis process has b...
