N2 - Owing to the unique physical properties, nanographene platelets could act as a good recombination inhibitor for functional materials. In this study, various concentrations of nanographene platelets are introduced to ferromagnetic Fe3O4 nanoparticles to remove methylene blue in aqueous solution under ultrasonic irradiation. The coupling of nanographene platelets with Fe3O4 nanoparticles is formed using hydrothermal method. Compared to pure Fe3O4 nanoparticles, Fe3O4-nanographene platelets (Fe3O4-NGP) composites exhibited higher catalytic efficiency for methylene blue removal under ultrasonic irradiation. The catalytic efficiency increase with increasing nanographene platelets loading from 1 wt.% until 5 wt% and further decreased. From the scavenger technique, it is revealed that hole plays an important key role in sonocatalytic processes. The degradation efficiency decreased only 12% after 4 cycled.
