Two-dimensional Ag nanosheets show increased antibacterial ability in many cases. Herein, Ag nanosheets with a thickness of 1.5 nm were introduced into titania sol to fabricate Ag nanosheet@TiO₂ antibacterial membranes. The prepared membrane possessed a molecular weight cutoff of 22,163 Da and a high permeance of 236 L/(m² h bar). Furthermore, the membrane presented good separation performance in the filtration of inulin extract. The transmittance of inulin reached 95%, and the decolorization rate reached 65%. Benefitting from the antibacterial properties of the Ag nanosheets, the membrane not only maintained a high stable flux and a low flux decay rate but also had good antifouling and antibacterial properties for inulin purification. Thus, it is promising for inulin purification applications.

Ag纳米片@TiO ₂菊粉纯化抗菌膜的制备

二维银纳米片在许多情况下显示出增强的抗菌能力。在此，将厚度为1.5nm的Ag纳米片引入二氧化钛溶胶中以制备Ag纳米片@TiO ₂抗菌膜。制得的膜的截留分子量为22,163 Da，高磁导率为236 L /（m ^2）h bar）。此外，该膜在菊粉提取物的过滤中表现出良好的分离性能。菊粉的透射率达到95％，脱色率达到65％。得益于Ag纳米片的抗菌特性，该膜不仅保持了高稳定的通量和低的通量衰减率，而且还具有用于菊粉纯化的良好的防污和抗菌性能。因此，对于菊粉纯化应用是有希望的。
