英文摘要	With the rapid development of multiple functional nanozymes, the research on the unique characteristic, contributing to the enzyme-like activity, is essential for us to construct mimic enzymes with outstanding activity. Herein, 2D Co-V mixed metal oxides (MMOs) are prepared through Co-V layered double hydroxide (LDH) precursor. The single phase of Co-V LDHs is prepared by controlling the dosage of hexamethylenetetramine accurately in the coprecipitation system. After calcinated at 400 degrees C, the obtained Co-V MMOs, composed of Co3V2O8 and Co3O4, still inherite the microtopography of nanosheets from the precursor, which have superior surface properties to enhance the peroxidase/oxidase (POD/OXD)-like activity. 2D Co-V MMO nanosheets have excellent bactericidal properties in the presence of H2O2 as low as 1 mu M. The enhanced catalytic performances are attributed to unique hybrid nanosheets architecture and synergistic effect of two active components, ranking the hybrid nanostructure as a promising antibacterial material.
