| Sumario: | Heterogeneous photocatalysis using TiO2 is a degradation technique for organic pollutants present in wastewater effluents. Previous studies report that the UV / TiO2 process is capable of efficiently decomposing various chlorinated alkenes and other organic compounds. Previous studies have shown that the use of nanoparticles improves photoactive activities relative to their bulk phase counterparts. The incorporation of transition metal dopants in the TiO2 structure can influence the performance of these photocatalysts by modifying the gap energy This work presents the results of the synthesis of solid solutions Ti1-xMnxO2, where 0.02≤x≤0.7, by using the sol-gel technique. X-ray diffraction studies showed the stability of the anatase phase at the different concentrations of Mn2 + analyzed (Ti1-xMnxO2; x = 0.02-0.05) at 500 ° C the nanocrystalline nature of the materials was verified. The band gap energies showed a decrease in their values as the manganese concentration increases. |
