摘要：

In this work, the effect of Bi/Ag double quantum dots on plasmon resonance and PMS activation was investi-gated. Bi/Ag double quantum dots were generated in situ on hollow Bi2MoO6 microspheres by stepwise irra-diation using a high-energy & beta; electron beam. The formation of Bi/Ag DQDs greatly optimized the drawbacks of Bi2MoO6 in terms of light absorption. Synergistic introduction of DQDs greatly reduced the band gap from 2.72 eV to 2.12 eV. The Bi-Ag@Bi2MoO6 -400/PMS system degraded ciprofloxacin with kinetic constants 10 and 12 times higher than those of the Bi@Bi2MoO6/PMS and Bi2MoO6/PMS...
