To use solar energy effectively, BiOX (Cl, Br, I) nanosheets with reasonable band gap structure were prepared by ultrasonic assisted hydrothermal method. The prepared BiOX (Cl, Br, I) nanosheets removed 90% of CBZ within 5 min, showing rapid degradation kinetic of 0.3858 min(-1). The improved photocatalytic activities can be due to the reduced recombination of photoinduced electron-hole pairs, strong visible-light absorption ability, large surface area and pore. Radicals experiments indicated that the BiOX (Cl, Br, I) generated main holes (h(+)) and minor electrons (e(-)) to degrade CBZ. These results demonstrated the good feasibility of BiOX (Cl, Br, I) nano-sheets in the degradation of CBZ under simulated solar light irradiation.
