研究目的
Investigating the multifunctional capabilities of MIL-88B(Fe)–Ag/TiO2 nanotubes/Ti plates as a photocatalyst, adsorbent, and disinfectant in water treatment.
研究成果
The MIL-88B(Fe)–Ag/TiO2 nanotubes/Ti plates demonstrated high efficiency in removing organic, inorganic, and biological pollutants from water, showcasing their potential as a multifunctional solution for water treatment. The cooperative effect between MIL-88B(Fe) and Ag/TiO2 nanotubes/Ti was key to their enhanced performance.
研究不足
The study focused on specific pollutants (Pb2+, Cd2+, MO, and E. coli) and conditions (UV light irradiation), which may not cover all potential water treatment scenarios. The scalability and long-term stability of the plates in real-world applications were not addressed.
1：Experimental Design and Method Selection:
The study involved the preparation of MIL-88B(Fe)–Ag/TiO2 nanotubes/Ti plates via dip-coating process and evaluated their performance in pollutant removal from aqueous solutions through adsorption, photocatalytic degradation, and antibacterial effects.
2：Sample Selection and Data Sources:
Heavy metal ions (Pb2+ and Cd2+), methyl orange dye (MO), and Escherichia coli (E. coli) were used as pollutants.
3：List of Experimental Equipment and Materials:
Titanium plates, MIL-88B(Fe), AgNO3, DMF, FeCl3·6H2O, H2BDC, and other chemicals were used. Equipment included a Fourier transform infrared spectrophotometer, field-emission scanning electron microscopy, and atomic absorption spectrophotometer.
4：Experimental Procedures and Operational Workflow:
The plates were prepared and characterized, followed by testing their adsorption, photocatalytic, and antibacterial activities under controlled conditions.
5：Data Analysis Methods:
The data were analyzed using Langmuir and Freundlich isotherm models for adsorption, and pseudo-first-order kinetics for photocatalytic degradation.
