Titanium dioxide (TiO2) film was prepared on activated carbon fibre (ACF) by hydrolysis technique, using sulphate titanium as raw material. Based on the techniques of photo catalytic degradation using TiO2/ACF, and 254nm UV-ray as the light sources, aqueous phenol solution of 40mg/L was photo catalytic decomposed over TiO2 film. The result showed that TiO2/ACF exhibited a degradation efficiency of...
The supported catalyst was prepared with transitional metal Co as the active component and the granular active carbon as the carrier. The catalytic wet air oxidation of methyl orange simulated wastewater with chlorine dioxide as oxidant. The optimal conditions were as follows:pH was 2, the dosing quantity of chlorine dioxide was 24 mg/L and catalyst was 60·g/L-1, reaction time was 60 min, the maximum...
Degradation of phenol by an electrochemical heterogeneous catalytic process was applied in packed bed electrolytic reactor with graphite electrode. The catalyst was characterized by SEM and the effects of pH, the applied potential and Na2SO4 on the efficiency of the electrochemical oxidation phenol process were also studied. It was found that the optimal condition was an applied potential of 25V,...
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...
