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 Fe{sub 3}O{sub 4} nanoparticles to remove methylene blue in aqueous solution under ultrasonic irradiation. The coupling of nanographene platelets with Fe{sub 3}O{sub 4} nanoparticles is formed using hydrothermal method. Compared to pure Fe{sub 3}O{sub 4} nanoparticles, Fe{sub 3}O{sub 4}–nanographene platelets (Fe{sub 3}O{sub 4}–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.
