“…Similar to the examples of the addition of plasmonic systems with the ferrites, Ag/AgCl was impregnated onto sepiolite clay which was modified with hydroxy iron (Ag/AgCl/Fe‐S) ( Liu et al, 2017 ). This catalyst exhibited excellent activity in degrading BPA.…”

Heterogeneous Fenton catalysts are emerging as excellent systems for applications related to water purification. In this review, recent trends in the synthesis and application of heterogeneous Fenton catalysts for the abatement of organic pollutants and disinfection of microorganisms are discussed. It is noted that as the complexity of cell wall increases, the resistance level towards various disinfectants increases and it requires either harsh conditions or longer exposure time for the complete disinfection. In case of viruses, enveloped viruses ( e.g. SARS-CoV-2) are found to be more susceptible to disinfectants than the non-enveloped viruses. The introduction of plasmonic systems with the Fenton catalysts broaden the visible light absorption efficiency of the hybrid material, and incorporation of semiconductor material improves the rate of regeneration of Fe(II) from Fe(III). A special emphasis is given to the use of Fenton catalysts for antibacterial applications. Composite materials of magnetite and ferrites remain a champion in this area because of their easy separation and reuse, owing to their magnetic properties. Iron minerals supported on clay materials, perovskites, carbon materials, zeolites and metal-organic frameworks (MOFs) dramatically increase the catalytic degradation rate of contaminants by providing high surface area, good mechanical stability, and improved electron transfer. Moreover, insights to the zero-valent iron and its capacity to remove a wide range of organic pollutants, heavy metals and bacterial contamination are also discussed. Real world applications and the role of natural organic matter are summarised. Parameter optimisation (e.g. light source, dosage of catalyst, concentration of H 2 O 2 etc. ), sustainable models for the reusability or recyclability of the catalyst and the theoretical understanding and mechanistic aspects of the photo-Fenton process are also explained. Additionally, this review summarises the opportunities and future directions of research in the heterogeneous Fenton catalysis.

“…Some researchers have reported that Ag/AgCl/Fe-S plasmonic catalyst could effectively degrade bisphenol A in photo-Fenton system under visible light irradiation (Liu et al, 2017c). Further, Zhu et al (2018b) reported that a novel photo-Fenton catalyst of Ag/AgCl/ferrihydrite could degrade bisphenol A as well, which revealed that the loading of Ag/AgCl could accelerate the conversion of Fe 3+ /Fe 2+ by the photo-generated electrons transferring from Ag nanoparticles owning to the surface plasmon resonance (SPR) effect.…”

Over the past few decades, Fenton process has been widely studied in environmental remediation. Due to the low efficiency of iron ions recycling, the Fenton efficiency has been seriously impeded for practical application. On this condition, with combination of photocatalysts, it is expected to fully use photo-generated electrons, thus enhancing the photo-Fenton efficiency. This synergistic methodology has assisted many researchers to remove various categories of organic pollutants in discharged wastewater or achieve gas conversion. This comprehensive review describes some significant advances with respect to presentative semiconductors (e.g., TiO 2 , g-C 3 N 4 , graphene, BiVO 4 , ZnFeO 4 and BiFeO 3 , etc.) including their preparation methods, characterization and applications in environmental remediation (e.g., organic removal, bacteria disinfection, membrane separation, and gas conversion). The mechanism is preferentially discussed. Possibly future development and its correlated potential challenges are specifically proposed and discussed in this review.

A series of novel anatase TiO2@MIL-101(Cr) composite was synthesized by solvothermal method for photocatalytic degrading bisphenol A (BPA). Compared with pure TiO2 and MIL-101(Cr), these composites exhibited superior catalytic performance for the BPA photocatalytic degradation. The characterization results determined the chemical structure and combination between TiO2 and MIL-101(Cr). The optical properties of the composites demonstrated enhanced catalytic efficiency with effectively separating the electron-hole pair and narrowing band gap. Moreover, the TiO2 amount and surface area in the composites jointly influenced the activity of photocatalytic degradation of BPA, which, meanwhile, was evaluated by changing the initial pH, catalyst dosage and initial BPA concentration. Under optimal condition, 59% TiO2@MIL-101(Cr) could reach 99.4% BPA degradation and the corresponding rate constant was 0.0138 min-1 in 240 min under UV irradiation. Furthermore, TiO2@MIL-101(Cr) possessed the excellent stability and was reusable. The reasonable pathway of BPA degradation was proposed based on the detected intermediates during the degradation, where the oxidative radicals •O2 − played a dominant role.
