To investigate the photocatalytic activity of metal ion doped TiO2 synthesized with sol-gel auto-igniting synthesis (SAS) method, Ag-TiO2 photocatalyst was synthesized with TiCl4 as raw materials, citric acid as combustion agent, ammonium nitrate as assistant. Methylene blue was degraded with synthesized catalyst illuminated by UV light and sun light separately. Results showed that the photocatalytic...
Fe(III)/TiO2 catalysts for sonocatalytic degradation of reactive blue 4 (RB4) dye was developed using sol-gel method. The Fe (III) loadings were varied from 0-1.0 mol% with a calcination temperature of 500°C. The degradation performance was conducted using an ultrasonic bath with the power and frequency of 50 W and 35 kHz, respectively. The combination of 0.4 mol% of Fe (III)/TiO2 under ultrasonic...
Activated carbon (AC) supported titanium dioxide (TiO2 ) photocatalyst (TiO2/AC) was prepared by two-step sol-gel process. Crystal structure, and surface morphology of TiO2/AC were characterized by X-ray diffraction (XRD), N2 adsorption-desorption isotherm measurements (BET) and scanning electron microscopy (SEM), respectively. The results show that average crystal size of TiO2 in 11% TiO2/AC catalyst...
