摘要Harvesting a remarkable antibacterial performance is a major point to choose enzymatic catalytic and photocatalytic coupling catalysts. Here, Co-Mo-S mixed metal sulfides (MMSs) were composed by tailoring the composition and energy of metal organic framework (MOF)-based precursors. When n(Co)/n(Mo) = 1:1, Co/Mo-MOF is in the lowest energy state and the vulcanized CoS2/MoS2 nanosheets (NSs) exhibit the best enzymatic property. With the inherent photocatalytic activity, CoS2/MoS2 NSs can degrade more than 90% of methylene blue, methyl orange, rhodamine B, and tetracycline hydrochloride within 1 h. Promoted by intrinsic photocatalytic properties, CoS2/MoS2 NSs exhibit outstanding mimic enzyme-mimicking abilities in a neutral medium, which solve the big problem that nanozymes can only work in acidic environments. Due to the collaboration of enzymatic and photocatalytic catalysis, center dot O-2(-) can be generated in a neutral, no H2O2, and dark system, which can effectively kill Escherichia coli and Staphylococcus aureus. In all, the design of MOFs with adjustable compositions, the breakthrough of enzymatic catalysis working in a neutral medium, and the innovation of sterilization independent of external conditions encourage the utilization in an open environment and the construction of multifunctional materials in biotechnology, biosensors, and biomedicine.
