TiO₂ nanoparticles were efficiently doped with Mn applying microwave-assisted synthesis method. Anatase phase was confirmed by XRD pattern, which did not exhibit the peaks associated with MnOx contamination. Raman spectroscopy showed a displacement of up to 5 cm⁻¹ in the O-Ti-O vibrational mode, suggesting that Ti was replaced by Mn. Oxidation state (Mn³⁺) was confirmed via high-resolution XPS spectrum of Mn 2p energy level. Incorporation of Mn into the TiO₂ network resulted in increased surface area (64.6 m² g⁻¹), average particle size up to 16 nm, and bandgap reduction of up to 43 %. The photocatalytic properties of the materials were investigated through Prozac® degradation and improvement of up to 14 % (Ti-0.73 Mn) and 26 % (Ti-0.38 Mn) was seen on comparing doped TiO₂ versus pure TiO₂ during photocatalysis. Furthermore, after Prozac® photodegradation, TFMP was identified as the main by-product while MAEB and PPMA (other by-products) were seen to compete with each other in the degradation mechanism. In addition to the quantitative analysis done for Prozac®, TFMP, MAEB, and PPMA, LC MS-Q-TOF analysis was performed, confirming that in the presence of Mn-doped TiO₂, specific by-products were formed, probably due to more oxidizing species being present in this reaction system. The present study has shown unprecedented evidence that the application of TiO₂ nanoparticles efficiently doped with Mn promotes Prozac® degradation by specific mechanisms.

微波辅助合成法将TiO ₂纳米颗粒有效地掺入了Mn。通过XRD图证实了锐钛矿相，该图没有显示出与MnOx污染相关的峰。拉曼光谱在O-Ti-O振动模式下显示最大5 cm ^-1的位移，表明Ti被Mn取代。通过Mn 2p能级的高分辨率XPS光谱确定了氧化态（Mn ³⁺）。Mn加入Ti​​O ₂网络导致表面积增加（64.6 m ²  g ^-1），平均粒径最高达16 nm，带隙减少最高达43％。通过降解降解来研究材料的光催化性能，在光催化过程中比较掺杂的TiO ₂与纯TiO ₂时，可以看到高达14％（Ti-0.73 Mn）和26％（Ti-0.38 Mn）的改善。此外，经过Prozac®光降解后，TFMP被确定为主要副产物，而MAEB和PPMA（其他副产物）在降解机理上相互竞争。除了对Prozac®，TFMP，MAEB和PPMA进行定量分析外，还进行了LC MS-Q-TOF分析，证实存在Mn掺杂的TiO ₂，形成了特定的副产物，可能是由于该反应系统中存在更多的氧化物质。本研究显示了空前的证据，表明有效掺杂锰的TiO ₂纳米颗粒的应用通过特定机制促进了Prozac®降解。
