N2 - In this study, the catalytic performance of the ZrO2 nanoparticles is enhanced by combining ultrasonic radiation with graphene material addition. The structural, morphological and surface properties of sol-gel synthesized ZrO2 nanoparticles with three different annealing temperatures (350°C, 550°C, and 750°C) were investigated using various characterization methods, including X-Ray Diffraction, Transmission Electron Microscope measurements and Brunauer-Emmett-Teller measurements. The result show that if the annealing process does not take place, ZrO2 nanoparticles have an amorphous structure. The formation of the crystalline structures of the tetragonal phase of the nanoparticle begins at an annealing temperature of 550°C. The highest sonocatalytic performance of nanoparticles is achieved at an annealing temperature of 550°C. The ZrO2/graphene nanocomposites were produced via co-precipitation methods at all annealing temperatures. The sonocatalytic activities in the presence of ZrO2/graphene nanocomposite indicate an enhancement, compared with ZrO2 nanoparticles. ZrO2 with and without graphene composites shows a level of stability that would allow reuse. A reasonable catalysis mechanism of ZrO2 with and without graphene composites is proposed.
