Objective:Silver nanoparticle-ZIF-67 nanocomposite(Ag-ZIF-67p)was prepared by ultrasonic reduction method.The degradation effect of oxytetracycline(OTC)was measured to investigate its photocatalytic performance.Methods:ZIF-67p(ZIF-67 nanopinnas)with large specific surface area was prepared by ultrasonic method,and Ag-ZIF-67p composite was obtained by reducing the metal precursor AgNO3 and loading nano-scale Ag particles onto ZIF-67 shell pinna.The materials were characterized by SEM,TEM,XRD,XPS,etc.,and the degradation effect of composites on OTC under different conditions was investigated by photometry.Results:Due to the synergistic properties of large porosity and surface area,as well as the high conductivity and excellent catalytic activity of Ag nanoparticles,ZIF-67 had a synergistic catalytic effect on oxytetracycline degradation.Conclusion:Ag-ZIF-67p could be used as catalytic material for degradation of oxytetracycline.
