Metal−organic frameworks (MOFs) are widely used to mimic enzymes for catalyzing chemical reactions; however, low enzyme activity limit their large-scale application. In this work, gold nanorods/metal−organic frameworks (Au NRs/Fe-MOF) hybrids were successfully synthesized for photo-enhanced peroxidase-like catalysis and surface-enhanced Raman spectroscopy (SERS). The enzyme-like activity of Au NRs/Fe-MOF hybrids was significantly enhanced under localized surface plasmon resonance (LSPR), because the hot electrons produced on Au NRs surface were transferred into Fe-MOF, activating the Fenton reaction by Fe 3+ /Fe 2+ conversion and preventing the recombination of hot electrons and holes. This photo-enhanced enzyme-like catalytic performance was investigated by X-ray photoelectron spectrometry (XPS), electrochemical analysis, activation energy measurement, and in situ Raman spectroscopy. Afterward, Methylene Blue (MB) was chosen to demonstrate the photo-enhanced peroxidase-like performance of Au NRs/Fe-MOFs. The Au NRs/Fe-MOF caused chemical and electromagnetic enhancement of Raman signals and exhibited a great potential for the detection of toxic chemicals and biological molecules. The detection limit of MB concentration is 9.3 × 10 −12 M. In addition, the Au NRs/Fe-MOF hybrids also showed excellent stability and reproducibility for photo-enhanced peroxidase-like catalysis. These results show that nanohybrids have great potential in many fields, such as sensing, cancer therapy, and energy harvesting.

“…5, the strong EPR signal corresponding to DMPO-˙OH with an intensity ratio of 1 : 2 : 2 : 1 was observed when the Ti/RuO 2 –IrO 2 @Pt electrode was used in the PFOA degradation processes. 52 While the intensity of the DMPO-˙OH signal was decreased obviously when Ti/RuO 2 –IrO 2 –Pt and Ti/RuO 2 –IrO 2 commercial electrodes were used. Although ˙OH cannot decompose PFOA directly, its sufficient generation can ensure the reaction of ˙OH with subsequent intermediates, thus accelerating the mineralization process of PFOA.…”

“…PFOA is chemically stable and is resistant to many traditional techniques due to its strong C–F bond and high oxidation potential, but recently electrochemical oxidation has been proved to be an effective method for degrading PFOA in an aqueous solution. 3,52 The electrochemical oxidation reactivity of the Ti/RuO 2 –IrO 2 @Pt electrode to PFOA was evaluated in this research, as shown in Fig. 4.…”

“…91% of PFOA mineralization could be reached in 2 h with solar photo-electro-Fenton (SPEF) like technology (Fig. 3e) (Wang et al, 2021b). This latter combination improved the removal efficiency of EF due to synergistic effect of light towards H2O2 decomposition into • OH and Fe(II) regeneration.…”

The electro-Fenton (EF) process is a powerful electrochemical advanced oxidation process. Its development has progressed over the past three decades as a clean and effective technique for wastewater treatment. Even though conventional EF has been shown to be a powerful process for efficient degradation/mineralization of toxic and/or persistent organic pollutants; it still suffers from some downsides for industrial-scale development. Recently, research has focused on improving its effectiveness and relevance, mainly by modifying certain operating parameters; improvements in electrode material and reactor configuration, as well as coupling with other treatment methods. Therefore, this review evaluates the current state of the EF process and presents the most recent advances such as 3D-EF, chelate-EF, self-powered EF, pulsed current EF, bio-EF, sono-EF, sulfite-EF, pyrite-EF, and ferrate-EF in addition to its emerging applications like disinfection, generation of value-added products, and removal of emerging pollutants from water. The suitability of different modified or hybrid-EF processes is discussed based on their performance in H2O2 generation, degradation kinetics, mineralization efficiency and cost effectiveness. This review article is intended to be comprehensive, critical and of general interest, covering recent developments and advances in EF process with the aim of providing a powerful method for the treatment of wastewater polluted with biorecalcitrant pollutants.
