摘　　要：The development of effective visible and near-infrared photocatalysts is highly promising in the current field of photocatalysis.Herein,carbon dots/ZnFe_(2)O_(4)(CDs/ZFO)with coating zero dimensional(0D)CDs on the surface of three dimensional(3D)yolk-shell ZFO spheres was designed and synthesized via a selftemplated solvothermal method.The as-prepared CDs/ZFO composites displayed outstanding visible and near-infrared photocatalytic degradation activity of tetracycline(TC),and the optimal 3%CDs/ZFO sample with loading 3%(mass)CDs displayed the highest photocatalytic TC degradation ability under visible light(79.5%within 120 min)and near-infrared light(41%within 120 min).The enhancement of photocatalytic activity for CDs/ZFO composite is mainly ascribed to the fact that 0D/3D yolk-shell CDs/ZFO structure not only effectively reflect the incident light to increase the utilization efficiency of solar light,but also utilize the up-conversion photoluminescence and electronic conductivity properties of CDs to broaden sunlight absorption range and promote separation and transfer of electron-hole pairs.
