摘要	The development of effective and low-cost enzyme-like nanomaterials is an essential issue for antibacterial applications. Herein, novel ultrathin Ni-V mixed metal oxides (MMOs) doped with sulfur(S) were successfully designed. After calcination with S powder in a N-2 atmosphere instead of in the air without S powder, the results proved that the obtained S-doping Ni-V MMOs remain ultrathin (5 nm in thickness) with much more vacancies and enhance oxidase (OXD) and peroxidase (POD) mimic activities sharply. More importantly, Ni-V MMO with a Ni/V molar ratio of 2 : 1 calcinated at 400 degrees C in the presence of sulfur shows the best OXD/POD mimic activity. The S-doping Ni-V MMOs also exhibit an antibacterial action on mode Gram-negative bacteria via generating ROS (mainly O-2(-)) in the presence of H2O2. It is also easily performed and highly specific. The unique 2D hierarchical nanostructure and sulfur doping endow the S-doping Ni-V MMO with abundant active sites and superb OXD/POD-like activity. The strategy expands the possibilities for boosting the catalytic activity of LDH-derived MMO nanomaterials.
