摘要

The small Zeolite Imidazole Framework-8 (ZIF-8) crystal was synthesized rapidly by the in situ growth method via dilute zinc-containing solution. ZIF-8 is a kind of traditional antibacterial material with high antibacterial performance. However, the synthesis time in the common synthesis for ZIF-8 material lasts not less than 24 h, with the disadvantage of aggregation and inefficient, which limit its application. The synergism of the in situ growth method via dilute zinc-containing solution can effectively abbreviate the synthesis time and promote antibacterial effect. ZIF-8(120 nm) exhibited the best antibacterial activity compared to the control samples, and its inhibitory rate (in 6 h) of E.coli is 85.1% —25.9% higher than that of the larger control sample ZIF-8 (1000 nm) and the inhibitory rate of S. aureus reaches 79.1%—27.8% higher than that of ZIF-8 (1000 nm). Characterization results including XRD, FT-IR, SEM, BET and TEM also confirmed the successful synthesis of small ZIF-8 crystals. Moreover, XPS data and DFT calculation demonstrated that the small ZIF-8 crystals promote the release of zinc ions, thereby enhancing the bacteriostatic effect.
