摘要 | Marine biofouling is an expensive problem that needs evolved chemical or physical antifouling strategies. However, most of the current antifouling materials that would damage the environment through metal leaching and bacteria resistance are being halted. Nanozyme is one kind of environmental antifouling materials through generating reactive oxygen species (ROS). We prepared various contents of CeO(2)that could uniform disperse compounding with Co(3)O(4)and CoAl(2)O(4)to form a stable Co-Al-Ce mixed metal oxide (MMO) by a layered double hydroxide derived method. We find that coupling with CeO(2)can improve the peroxidase (POx) activity. When the molar ratio of Ce is 2.5% and the calcination temperature is 200 degrees C, the POx activity of Co-Al-Ce MMO is the best caused by the good dispersion of catalytically active components and the high specific area (150.10 +/- 4.95 m(2)/g). This novel Co-Al-Ce MMO also exhibits an antibacterial mode of action Gram-negative bacteria in near-neutral pH solution through generating ROS (mainly center dot O-2(-)) in the presence of H2O2. Ce containing MMO can be utilized as potential green marine antifouling material. |
