چکیده مقاله:
In this study, a chemical method including TiCl4, Al(NO3)3, ethanol amine, ethyl acetoacetate and aqueous ammonia were used for the fabrication of TiO2-Al2O3 nano-composite. The as prepared nano-composite was characterized applying the XRD, FE-SEM and TEM techniques. The photocatalytic behavior of TiO2-Al2O3 nano-composite was evaluated in the photo-catalytic degradation of methyl orange under UV irradiation technique. The effect of various parameters including catalyst dosage, dyes concentration, pH and temperature on the degradation of methyl orange was investigated. The degradation rate was efficiently increased as the concentration of catalyst was decreased. The optimum dosage of methyl orange was found to be 10 mgL-1. In addition, we found that pH can significantly enhance the photocatalytic degradation of methyl orange dye
