Abstract

The objective of this research is to study the fotodegradation of phenol by titanium dioxide and titanium silicate mesoporous-mesostructure accelerated by hydrogen peroxide (H2O2). Photodegradations were carried out in stirred slurries of mesoporous-mesostructure titanium dioxide and titanium silicate: 0.15 g TiO2-layered macrostructure, 0.35 g TiO2/MCM-41 and 0,5 g Ti-MCM-41 in deionized water respectively. Phenol solution (0,5 g/L) was illuminated by 160 W from mercury lamp at times various: 20, 40, 60 and 80 minute. The results show that TiO2-layered mesostructure followed by TiO2/MCM-41 are the two most active photocatalyst, while Ti-MCM-41 is not active photocatalyst. Organic substances produced from phenol fotodegradation include phenol → p-benzoquinon, hydroquinon →catecol → maleic acid → acetic acid and formic acid → water and carbon dioxide.
