摘要

在研究去除废水中难降解有机污染物的可持续方法时,可见光响应光催化技术引起了人们的极大兴趣。因此,人们对具有更强太阳光吸收能力和更高电荷载流子分离能力的特制光催化剂有很高的要求。本研究通过共沉淀法制备了纯钴铁氧体(CoFe2O4)及其掺氟材料(F-CoFe2O4)。掺氟材料被整合到二维 MXene 中,通过超声法设计出复合材料(F-CoFe2O4@MXene)。粉末 XRD、傅立叶变换红外光谱、扫描电镜、电离辐射分析、紫外可见吸收和光致发光光谱等多种技术对制备的催化剂的结构、表面形貌、化学成分和光学性质进行了表征。通过降解选作模型污染物的水晶紫(CV)染料和苯甲酸(BA),对光催化潜力进行了评估。与纯材料和掺杂材料相比,复合材料的催化效率明显提高。在太阳光照射 140 分钟后,CV 和 BA 的降解率分别达到 91% (0.0138 min-1) 和 87% (0.0133 min-1)。该复合材料显著的催化潜力与二维 MXene 中的氟掺杂和整合有关,氟掺杂和整合增强了二维 MXene 对可见光的吸收,降低了分离电荷(e-/h+)的快速重组率。通过对反应动力学、光降解过程中的主要催化物种以及催化剂的稳定性等方面的系统研究,揭示了所设计的 F-CoFe2O4@MXene 的光催化潜力。此外,还探讨了催化剂的实时适用性。

Fluorine-doped cobalt ferrite integrated into 2D MXene with extended solar spectrum response and boosted charge separation for the removal of recalcitrant organic pollutants
In investigating sustainable methodologies for removing recalcitrant organic pollutants from wastewater, visible-light-responsive photocatalysis has drawn considerable interest. Therefore, intentionally engineered photocatalysts with enhanced solar-light-absorption capacity and boosted charge carrier’s separation are highly demanded. In the present attempt, pure cobalt ferrite (CoFe2O4) and its fluorine-doped counterpart (F-CoFe2O4) were fabricated via co-precipitation. The fluorine-doped material was integrated into the 2D MXene to design the composite (F-CoFe2O4@MXene) by the ultrasonication method. The structure, surface morphology, chemical composition, and optical properties of the as-prepared catalysts were characterized by various techniques, including powder XRD, FTIR, SEM, EDS, UV–vis absorption, and photoluminescence spectroscopy. The photocatalytic potential was estimated by degrading crystal violet (CV) dye and benzoic acid (BA), which were selected as model pollutants. The composite material showcases significantly enhanced catalytic efficiency relative to the pure and doped materials. Under solar light exposure for 140 min, 91 % (0.0138 min−1) and 87 % (0.0133 min−1) of CV and BA degradation were achieved, respectively. The remarkable catalytic potential of the composite material corresponds to the fluorine doping and integration to the 2D MXene, which has enhanced its visible-light absorption and lowered the rapid recombination rate of the separated charges (e-/h+). Systematic studies, including reaction kinetics, dominating catalytic species in photodegradation, and stability of the catalyst, were followed through to disclose the photocatalytic potential of the designed F-CoFe2O4@MXene. Furthermore, the real-time applicability of the catalyst has been explored.

期刊介绍: Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
