Abstract
State-of-the-art Fenton-like reactions are crucial in advanced oxidation processes (AOPs) for water purification. This review explores the latest advancements in heterogeneous metal-based catalysts within AOPs, covering nanoparticles (NPs), single-atom catalysts (SACs), and ultra-small atom clusters. A distinct connection between the physical properties of these catalysts, such as size, degree of unsaturation, electronic structure, and oxidation state, and their impacts on catalytic behavior and efficacy in Fenton-like reactions. In-depth comparative analysis of metal NPs and SACs is conducted focusing on how particle size variations and metal-support interactions affect oxidation species and pathways. The review highlights the cutting-edge characterization techniques and theoretical calculations, indispensable for deciphering the complex electronic and structural characteristics of active sites in downsized metal particles. Additionally, the review underscores innovative strategies for immobilizing these catalysts onto membrane surfaces, offering a solution to the inherent challenges of powdered catalysts. Recent advances in pilot-scale or engineering applications of Fenton-like-based devices are also summarized for the first time. The paper concludes by charting new research directions, emphasizing advanced catalyst design, precise identification of reactive oxygen species, and in-depth mechanistic studies. These efforts aim to enhance the application potential of nanotechnology-based AOPs in real-world wastewater treatment.

Abstract
Nowadays, due to the increasing threat of heavy metal ion pollution faced by the environment and living systems, the development of rapid and highly selective methods for the detection of chromium ions (Cr3+) has aroused increasing interest. In this study, copper ferrite nanoparticles (CuFe2O4) immobilized on reduced graphene oxide (CuFe2O4/rGO) were successfully fabricated by a simple co-precipitation method. The catalyst exhibits high peroxidase-like activity with 3,3',5,5'-tetramethylbenzidine (TMB) as a chromogenic matrix due to its large specific surface area, adsorption performance and abundant catalytic active sites. Based on the excellent peroxidase-like activity of CuFe2O4/rGO and its Cr3+-mediated inhibition controllability, a novel colorimetric assay for the heavy metal Cr3+ was created for the first time. Under optimal experimental conditions, CuFe2O4/rGO can be used as a peroxidase-like nanozyme to achieve the excellent detection of Cr3+ in the range of 0.1-25 μM, and the detection limit is 35 nM. The peroxidase-like CuFe2O4/rGO can provide a general catalytic platform for the application of biomimetic enzymatic catalytic systems and colorimetry, and a new approach has been established for the specific determination of the heavy metal Cr3+.

[PMID: 32712506 DOI: 10.1016/j.watres.2020.116200] [Citation(s) in RCA: 72] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Revised: 07/16/2020] [Accepted: 07/17/2020] [Indexed: 06/11/2023]
Abstract
Advanced oxidation processes (AOPs) have attracted much interest in the field of water treatment owing to their high removal efficiency for refractory organic contaminants. Graphitic carbon nitride (g-C3N4)-based catalysts with high performance and cost effectiveness are promising heterogeneous catalysts for AOPs. Most research on g-C3N4-based catalysts focuses on photocatalytic oxidation, but increasingly researchers are paying attention to the application of g-C3N4-based catalysts in other AOPs beyond photocatalysis. This review aims to concisely highlight recent state-of-the-art progress of g-C3N4-based catalysts in AOPs beyond photocatalysis. Emphasis is made on the application of g-C3N4-based catalysts in three classical AOPs including Fenton-based processes, catalytic ozonation and persulfates activation. The catalytic performance and involved mechanism of g-C3N4-based catalysts in these AOPs are discussed in detail. Meanwhile, the effect of water chemistry including pH, water temperature, natural organic matter, inorganic anions and dissolved oxygen on the catalytic performance of g-C3N4-based catalysts are summarized. Moreover, the reusability, stability and toxicity of g-C3N4-based catalysts in water treatment are also mentioned. Lastly, perspectives on the major challenges and opportunities of g-C3N4-based catalysts in these AOPs are proposed for better developments in the future research.
