Bi2WO6 photocatalyst was hybridized by graphite-like C3N4via facile chemisorption. After hybridization with C3N4, the photocatalytic activity of Bi2WO6 was obviously enhanced. A C3N4/Bi2WO6 photocatalyst hybridized with monolayer C3N4 exhibited the highest photocatalytic activity which was 68.9% higher than that of pure Bi2WO6. The enhanced photocatalytic activity of the C3N4/Bi2WO6 photocatalysts could be attributed to the synergetic effect between C3N4 and Bi2WO6. The photogenerated holes on the valence band of Bi2WO6 could transfer to the highest occupied molecular orbital of C3N4via the well developed interface, causing rapid photoinduced charge separation and enhancing the photocatalytic activity.
