Hypothesis
Can a flexible PAN/P25 multi-porous nanotubular membrane improve photocatalytic degradation and sterilization performance?
Conclusion
The PAN/P25-3 membrane achieved 96.1% degradation of Rhodamine B and 95.8% inactivation of E. coli, demonstrating excellent photocatalytic performance.
Supporting Evidence
- The PAN/P25-3 membrane showed the highest photocatalytic degradation efficiency.
- After five cycles, the PAN/P25-3 membrane maintained about 94% of its original photocatalytic performance.
- The unique multi-porous structure enhances light utilization and active site exposure.
Takeaway
Scientists made a special membrane that can clean dirty water really well by breaking down harmful stuff and killing germs.
Methodology
The membrane was created using electrospinning and solvothermal induction, and its photocatalytic activity was tested using Rhodamine B and E. coli.
Limitations
The study did not explore the long-term stability of the membrane in real-world conditions.
