Abstract
In this study, a novel boron�¢����graphene oxide�¢����TiO2(B�¢����GO�¢����TiO2) was synthesized by sol�¢����gel method. The structure and properties of nano particles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) spectroscopy. The analysis of the process was performed by varying four significant independent variables, including four numerical factors (concentration of 4-NP, dosage of photo catalyst, initial pH and reaction time). The experiments were conducted based on a central composite design (CCD) and analyzed using response surface methodology (RSM). The photo catalytic activity of samples was monitored by UV�¢����vis absorption measurements and chemical oxygen demand (COD) test. The results showed that degradation of 4-NP in acidic pH is more favored than in neutral and basic pH. The modified modes reduced recombination of photo generated electron and holes, and extended the absorption of TiO2 into the visible light. The photo catalytic properties of B�¢����GO�¢����TiO2is more effective than those of pure TiO2 and other modified TiO2. The removal efficiency of 4-NP for B�¢����GO�¢����TiO2, B�¢����TiO2and GO�¢����TiO2was about 100, 85 and 80%, respectively, and also removal efficiency of COD was about 85, 70 and 65%, respectively, under visible light irradiation and optimum condition (4-NP concentration=25 mg/l, concentration of photo catalyst = 1 g/l, amounts of COD= 300 mg/l and pH of 3 after 180 min).Biography
