We report on the fabrication of a Fe3O4@graphene/TiO2(F@G/TiO2) nanohybrid using a facile two-step hydrothermal method. Compared with either the binary graphene/TiO2(G/TiO2) or pure TiO2, the ternary F@G/TiO2nanohybrid exhibited an apparently improved performance for photocatalytic isopropanol (IPA) degradation, and the sample F1@G/TiO2(0.4 wt% Fe3O4and 0.2 wt% graphene) achieved the highest activity (262.5 μmoL/h for acetone evolution; 28.8 μmoL/h for CO2evolution) under an AM 1.5G solar simulator irradiation. In the F@G/TiO2nanohybrid, the magnetic field arisen from Fe3O4and the excellent electrical conductivity of graphene were believed to facilitate the separation and transport of photoinduced electrons and holes in TiO2. As a consequence, the synergetic effect could account for the enhanced photocatalytic activity of F@G/TiO2nanohybrid. Mechanistic study indicated that O2•−and hole were the main reactive oxygen species for photocatalytic IPA degradation.
