摘要：

为拓宽芬顿体系pH值的使用范围以高效降解水体中的染料,采用回流法制备多壁碳纳米管负载的十六氯铁酞菁 (FePcCl₁₆/MWCNTs)催化剂,以双氧水(H₂O₂)为氧化剂,在模拟太阳光照的作用下催化降解酸性橙7(AO7) 染料。借助扫描电子显微镜、透射电子显微镜、红外光谱仪、热重分析仪和X射线衍射仪等对催化体系的催化性能、影响因素和催化机制进行研究。结果表明:催化体系在酸性、无机盐及尿素环境中,对AO7的降解率均为100%,在中性环境中为97%,在碱性条件下为75%;该催化体系经5次循环使用后,对AO7的降解率仍在95%以上;催化体系中降解AO7的主要活性种为羟基自由基和超氧自由基,光照可促进活性种的产生而提高体系的催化性能。

Abstract:

In order to expand the pH value of the Fenton system to degrade dye efficiently, the catalyst FePcCl₁₆/multi-walled carbon nanotubes (FePcCl₁₆/MWCNTs), synthesized by means of FePcCl₁₆ loaded on MWCNTs via reflux with H₂O₂ as oxidant, was employed to degrade Acid Orange 7 dye (AO7) under simulated solar light irradiation. The catalytic performance, influencing factors and catalytic mechanism of the catalytic system were characterized by scanning electron microscope, transmission electron microscope, Fourier transform infrared spectrometer, thermogravimetric analyzer and X-ray diffractomer. The results show that the degradation rate of AO7 is 100% under acidic, inorganic salts and urea conditions in catalytic system, 97% under the neutral condition, and 75% under the alkaline condition. The degradation rate of AO7 is still above 95% after 5 cycles of the catalytic system. The results of catalytic mechanism show that the main active species of AO7 degradation in the catalytic system are hydroxyl radicals and superoxide radicals. Solar light irradiation promotes the production of active species to improve the catalytic performance of the system.
