Zn-Yb white carbon black with antibacterial properties was prepared by sol-gel method.The preferred preparation conditions were obtained via controlling single factor variable experiment:Zn ion concentration was 0.7mol/L,Yb ion concentration was 0.007mol/L,and reaction time was 1 hour.In this experiment,detecting antibacterial property of products via antibacterial experiment (Escherichia coli was used as a strain,and detected by a coating plate method).The product was characterized by SEM,EDS,BET,XRD,ICP and particle size analysis.The results shown that the structure of Zn-Yb was fluffy,the particle size of the material was small,the specific surface area was large and it was amorphous after doped Yb.The addition of Zn and Yb ions did not change the structure of the carrier.The antibacterial experiment manifested this material was favourable antibacterial property about Escherichia coli.The antibacterial rate of the material after adding Yb increased form 71% to 94%.The Yb was a synergistic antibacterial agent in the material.
