Abstract

In order to meet the green antibacterial and antifouling requirements of marine equipment，cerium oxide (CeO2) nanoparticles with haloperoxidase activity could be used as a new green and efficient antifouling agent，and graphene oxide (GO) loading was used to enhance the activity of CeO2 haloperoxidases mimicry.Herein，three kinds of GO-CeO2 composite materials with GO mass fractions of 1%，2%and 4%were successfully prepared by using GO as the supporting layer for the growth of CeO2 crystal nuclei by hydrothermal method.The antibacterial properties of GO-CeO2 with different GO contents based on the activity of haloperoxidase mimicry were discussed from the aspects of morphology，composition，activity and antibacterial properties of haloperoxidase mimicry.Results showed that in the GO-CeO2 composite with 2%(mass fraction) GO，the short-rod CeO2 was uniformly and densely distributed in the GO loading layer，which possessed the highest concentration of Ce3+ and oxygen vacancies，and the energy band gap was 2.76 eV.Additionally，the activity of haloperoxidase mimicry was the strongest，and the antibacterial rate reached 98.47%，which met the expected requirements of the new antifouling agent.Compared with commercial CeO2，GO-CeO2 composites had the stronger activity of haloperoxidase mimicry，providing a new reference for the application of CeO2 green and efficient new antifouling agents.

Key words： cerium oxide; graphene oxide; haloperoxidases mimicry; antifouling agent; synthesis; antibacterial properties
