研究目的
Investigating the synthesis and photocatalytic activity of MIL-125(Ti)/carbon nanotube nanocomposites for decolorization of colored wastewater.
研究成果
The MIL-125(Ti)/CNT nanocomposites showed higher photocatalytic dye degradation efficiency compared to MIL alone, with the process following zero-order kinetics. The nanocomposites were reusable over two cycles, indicating potential for practical applications in wastewater treatment.
研究不足
The study focuses on the photocatalytic degradation of a single model pollutant (Reactive Black 5) and the reusability of the catalysts was only tested over two cycles.
1：Experimental Design and Method Selection:
Hydrothermal method was used to synthesize MIL-125(Ti)/CNT nanocomposites with different amounts of CNT (0.01 g and 0.03 g).
2：01 g and 03 g).
Sample Selection and Data Sources:
2. Sample Selection and Data Sources: Reactive Black 5 (RB5) was used as a model pollutant. The synthesized nanomaterials were characterized by XRD, FTIR, TGA, BET, SEM, and zeta potential analyses.
3：List of Experimental Equipment and Materials:
BDC (1,4-benzenedicarboxylate), TTIP (Titanium tetraisopropoxide), DMF (Dimethyl Formamide), methanol, Reactive Black 5, carbon nanotube (CNT).
4：Experimental Procedures and Operational Workflow:
The synthesis involved dispersing CNT in PVP methanol solutions, adding BDC and TTIP, and subjecting to solvothermal conditions. Photocatalytic degradation experiments were carried out in a reactor with a UV lamp.
5：Data Analysis Methods:
Pollutant degradation kinetics were analyzed using zero-order, first-order, and second-order models.
