Efficient photocatalytic degradation of tetracycline hydrochloride by Fe-TiO2/MIL-101(Cr) nanocomposites under visible light
The misuse of antibiotics, including tetracycline hydrochloride (TCH), can easily lead to drug resistance and the decline of human immunity, which is extremely harmful to human health. In this paper, TiO2 was modified using two different techniques: semiconductor composite and metal ion doping. Fe-TiO2/MIL-101 (Cr) nanocomposite photocatalyst (FTM-x) was effectively prepared by solvothermal method and used for the degradation of TCH in water under visible light. The performance of ternary composite materials, in comparison to single or binary compounds, are improved by using an easy and convenient hydrothermal technique. Among them, FTM-2 showed efficient photodegradation and structural stability. After 120 min in visible light, FTM-2 removed 95.5 % of TCH, and the removal was maintained at 85 % after 4 cycles. The composite FTM-x was characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Raman, which proved the successful synthesis of the composite. Photoelectrochemical and photoluminescence (PL) analyses were used to examine the photoelectric properties of the prepared photocatalysts. The results suggested that optimizing the composites' photoresponse and electron-hole separation could be linked to improving the photocatalytic performance. The photocatalytic activity of superoxide radicals (O2−) and hydroxyl radicals (OH) was demonstrated to be mediated by free radical trapping investigations, which were utilized to determine the active components of the process.
期刊介绍：
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
