摘要	BiFeO3 nanoparticles were prepared via a polyacrylamide gel route. BiFeO3 - graphene nanocomposites were fabricated by mixing BiFeO3 nanoparticles and graphene into absolute ethanol solution followed by thermal drying. The TEM observation demonstrates that the BiFeO3 nanoparticles are well anchored onto graphene sheets. The photocatalytic activities of the as- prepared samples were evaluated by the degradation ofmethyl orange ( MO) under simulated sunlight irradiation. Compared to bare BiFeO3 nanoparticles, BiFeO3 - graphene nanocomposites exhibit enhanced photocatalytic activity. The outstanding photocatalytic performance is mainly ascribed to the efficient transfer of photogenerated electrons from BiFeO3 to graphene, thus leading to an increased availability of h(+) for the photocatalytic reaction. In addition, hydroxyl (.OH) radicals were detected by the photoluminescence technique using terephthalic acidas a probemolecule andare foundtobeproducedonthe irradiatedBiFeO(3) and BiFeO3 - graphene nanocomposites; in particular, an enhanced yield is observed for the latter.
