摘要

近年来，由于静电纺丝材料具有独特的功能特性，在过滤领域的应用得到了很大的发展。在不同温度下合成了含有TiO2颗粒的聚乙烯吡咯烷酮（PVP）静电纺丝膜。这些都被整合到膜中。利用FTIR-ATR和SEM技术对合成膜进行了表征。以文拉法辛为模型污染物，评价了膜的光催化活性。光催化实验证明了其光催化效率。结果表明，两种含TiO2的膜在降解文拉法辛时均表现出良好的光催化活性。经过90分钟的紫外线照射后，观察到高达85%的药物降解。这些结果突出了PVP膜在污染物去除方面的潜在应用。

Synthesis of electrospun polymer nanofiber membranes with TiO2 particles for the photocatalytic degradation of venlafaxine

In recent years, there has been an electrospun materials development increase for filtration applications due to their distinct functional properties. Electrospun membranes of polyvinylpyrrolidone (PVP) containing TiO₂ particles were synthesized with different temperatures producing different phases. These were incorporated into the membranes. The synthesized membranes were characterized using FTIR-ATR and SEM techniques. The photocatalytic activity of the membranes was evaluated using venlafaxine as a model pollutant. The photocatalytic efficiency was evidenced by photocatalysis tests. The results obtained showed that both membranes containing TiO₂ exhibited excellent photocatalytic activity in the degradation of venlafaxine. After 90 min of UV irradiation, a degradation of up to 85% of the drug was observed. These results highlight the potential use of PVP membranes for the pollutants removal.
