Effect of Zr+4 doping on characteristics and sonocatalytic activity of TiO2/carbon nanotubes composite catalyst for degradation of chlorpyrifos
Original language description
Nanotitania/carbon nanotubes composites were prepared using the sol-gel method with different nanotitania:carbon nanotubes ratios. The composite sample was modified with zirconium cation (IV). The prepared com-posites were characterized with different techniques using thermogravimetric analysis (TGA), nitrogen ad-sorption, transmission electron microscopy (TEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX),diffuse reflectance spectroscopy (DRS) and Fourier transform infrared spectroscopy (FTIR). Sonocatalytic de-gradation efficiency of the prepared sonocatalysts was tested for sonocatalytic degradation of chlorpyrifos atdifferent application conditions such as the effect of chlorpyrifos concentration, temperature, catalyst dosage,ultrasonic power and the presence of radiation light. Zirconium modified nanotitania/carbon nanotubes com-posite (ZCT10) shows the maximum sonocatalytic activity (91.5% after 60 min) and obeyed pseudo-first orderkinetic models. The optimum degradation efficiency was also confirmed at 2.0 g/L as catalyst dosage and in-crease with both of application temperature and ultrasonic power. The presence of radiation light can alsoenhance the activity of sonocatalysts. Catalyst reusability experiments showed that catalysts are well reusable fordegradation of chlorpyrifos by the sonocatalytic process.
