Abstract EN
Titanium dioxide (TD) and graphene oxide (GO) were synthesized by sol-gel and improved Hummers method, respectively.
This study shows the results of the incorporation through four different conditions (sol-gel, sol-gel and ultrasonic, annealed, and UV radiation, C1 to C4, respectively).
It was observed that a homogeneous incorporation of TD on sheets of GO was obtained satisfactorily.
The composites of TiO2/GO were characterized using different techniques such as X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), scanning transmission electron microscopy (STEM), energy dispersive X-ray spectroscopy (EDS), Raman spectroscopy, and infrared spectroscopy (IR).
The photocatalytic activity of the composites was determined from the degradation of the dye azo tartrazine using UV and solar radiation.
The best incorporation of TD nanoparticles on GO was obtained with condition C3 (thermal incorporation method) at a temperature of 65°C.
This shows a uniformity in the size and shape of the TD as well as an excellent adherence to the sheet of GO.
This addition is accomplished by ionic bonding in the presence of electrostatic Coulomb forces.
The C3 composite degraded the tartrazine dye using UV radiation and sunlight.
With the latter, the degradation time was three times faster than using UV light.
