摘要
摘要 本研究通过溶热合成法开发了一种介孔 Mn/Fe/N 掺杂氧化锌纳米复合材料,重点研究了其降解染料的光学和磁学潜力。傅立叶变换红外光谱分析确定了独特的官能团,而电离辐射X分析确认了其元素组成。BET 分析表明,由于介孔的存在,其表面积扩大了,这体现在 IV 型等温线上。紫外-可见光谱分析显示了红移和光带隙从 3.13 eV 减小到 2.68 eV,表明光吸收得到了改善。扫描电子显微镜(SEM)显示了独特的形貌,而 PL 研究则表明高掺杂样品中的电子-空穴重组减少了。SQUID 测量验证了纳米复合材料的铁磁特性。这些特性共同提高了纳米复合材料对刚果红和亚甲基蓝染料的光催化功效,为环境净化提供了可行的解决方案。
Study of Optical and Magnetic Properties of Solvothermally Synthesized Mn/Fe/N-Doped ZnO Nanocomposite for Advanced Dye Photodegradation
In this research, a mesoporous Mn/Fe/N-doped ZnO nanocomposite was developed via solvothermal synthesis, focusing on its optical and magnetic potentials for dye degradation. FTIR spectroscopy identified unique functional groups, while EDX analysis confirmed its elemental composition. BET analysis showcased an expanded surface area due to mesoporosity, evidenced by a type IV isotherm. UV-Visible spectroscopy revealed a red shift and optical band gap reduction from 3.13 to 2.68 eV, indicating improved light absorption. SEM provided insights into distinctive morphologies, and PL studies showed reduced electron-hole recombination in highly doped samples. SQUID measurements verified the nanocomposite’s ferromagnetic characteristics. These properties collectively enhance its photocatalytic efficacy against Congo red and Methylene blue dyes, presenting a viable solution for environmental clean-up.
