Application of Titanium-Silica-Graphite Composite Material for Photocatalytic Process of Methylene Blue

The use of TiO2 in the slurry system for the photocatalytic process has disadvantages. It causes the resistance of UV transmission because it is cloudy and the difficulty for obtaining the catalyst at the end of the process. Therefore, an attempt to overcome this was conducted by compositing TiO2 on...
