TỔNG HỢP NANO TITANIUM DIOXIDE VÀ ỨNG DỤNG TRONG KHÁNG KHUẨN

Tóm tắt

Nano titanium dioxide (TiO2) is an important material that has been extensively investigated due to its
uniqueness. A large number of efforts have been made to synthesize nano titanium dioxide materials using
different methods. In this work, nano TiO2 was successfully synthesized by the hydrothermal method under
acidic-base conditions using commercial TiO2 powder. Morphological and size information about the
synthesized material was determined using EDX and SEM analysis. EDX analysis provides the elemental
composition of the synthesized product. Nitrogen adsorption-desorption was used to determine the surface
area (Brunauer-Emmett-Teller (BET)), porosity, and capillary distribution of the material. The TiO2
nanoparticles were tested for their antibacterial activity against human pathogens such as gram-negative
Escherichia coli (E. coli) and gram-positive Staphylococcus aureus (S. aureus) using the paper ring
diffusion method on agar medium, yielding excellent results.
