N2 - The ZrO2/Nanographene platelets (NGP) composites with different NGP weight percents were successfully synthesized using two-step methods (sol-gel followed by coprecipitation methods). The structural properties of the composites were analyzed using X-Ray Diffraction (XRD), Energy Dispersive X-Ray (EDX), Transmission Electron Microscope (TEM), and Thermalgravimetric Analysis (TGA). The presence of NGP in the composites confirms by the graphitic-like structure in the XRD and layer-like structure in the TEM. Thermal stability of the composites tends to reduce with the incorporation of NGP. The catalytic performances of the composites were evaluated by three catalytic processes. The degradation of methylene blue as a model pollutant by the composites are monitored using UV-Vis Spectroscopy. The result shows that ZrO2 with 10 wt% of NGP exhibits the highest performance for all of three processes. The scavenger experiment shows that hole acts as an active species that play a role in the catalytic process of the composites.
