英文摘要 | In this study, heterogeneous Fenton-like catalyst, nano-Fe degrees encapsulated in hydrothermal carbon (Fe degrees/HTCC), was prepared via a green chemistry route, aiming at increasing the degradation efficiency of p-chlorophenol (4-CP) by controlling the stability of the catalyst and Fe(III)/Fe(II) cycling in the advanced oxidation process. The degradation of 4-CP by heterogeneous Fenton reactions was conducted with the assistance of visible light, which was monitored with the aid of the HPLC and total organic carbon analysis. The results revealed that Fe degrees/HTCC composite markedly enhanced both the degradation (100 %) and the mineralization efficiency (similar to 73.9 %) for 100 mg/L 4-CP within 60 min at pH 4.0. More importantly, the catalyst presented a high stability to resist the side oxidation, where the removal efficiency was maintained even after 5 successive cycling experiments. Electron spin resonance confirmed that in the presence of both HTCC and visible light irradiation greatly enhanced the production of center dot OH for the degradation and mineralization of 4-CP, which can he attributed to the enhancement of Fe(III)/Fe(II) cycling. This study paves a new way toward the rational design of Fe degrees-carbon composites as heterogeneous Fenton-like catalysts for potential applications into wastewater treatment. |
