摘要CuBi2O4 hierarchical microcuboids self-assembled from nanorods were synthesized via a coprecipitation method, and their growth process was investigated. The as-synthesized CuBi2O4 hierarchical microcuboids were decorated with AuAg alloy nanoparticles via a photocatalytic reduction method. The prepared samples were systematically investigated by XRD, SEM, TEM, XPS, UV-vis DRS, EIS, PL spectroscopy and photocurrent response. RhB was chosen as the target organic pollutant to evaluate the photocatalytic activity of the samples under simulated-sunlight irradiation. It is demonstrated that the prepared CuBi2O4 samples exhibit excellent photocatalytic activity toward the degradation of RhB. Furthermore, the decoration of AuAg alloy nanoparticles on CuBi2O4 hierarchical microcuboids leads to much enhanced photocatalytic performance of the resultant AuAg-CuBi2O4 composite. The main reason for this is that the recombination rate of photogenerated electron-hole pairs is decreased due to the electron transfer from CuBi2O4 microcuboids to AuAg nanoparticles, and thus more charges are able to participate in the photocatalytic reactions. The effect of ethanol (scavenger of center dot OH), BQ (scavenger of center dot O-2(-)) and AO (scavenger of h(+)) on the dye degradation and the yield of center dot OH was also investigated. Based on the experimental results, it is confirmed that center dot OH is the dominant reactive species responsible for the dye degradation. The underlying photocatalytic mechanism was discussed.
