“…Core-shell structure with porous carbon shell and TM core (TM@C) provides a possible method to immobilize TM component [21,22] without significant impact on the ORR selectivity on the outermost surface of carbon shell. The major downsides of typical TM@C structure are low metal accessibility and hindered mass transfer compared with TM/C configuration, which would greatly compromise the original Fenton activity of metals core without precise control in the porosity and thickness of outer carbon shell.…”

The heterogeneous electro-Fenton (EF) process is a promising wastewater treatment technology for the onsite production of H 2 O 2 and avoidance of iron sludge. However, the preparation of the cathode catalysts remains a challenge. Not only must the catalyst surface possesses active sites for both 2e − oxygen reduction reaction and heterogeneous Fenton reaction, preventing active metals from continuous leaching is also crucial to maintain its catalytic activity. Herein, a heterogeneous catalyst (rGO@Fe x P/C) with a vacuumized package-like structure, where carbon-supported iron phosphides (Fe x P/C) are tightly covered within interconnected reduced graphene oxide (rGO) sheets, is successfully prepared. The concentration of iron that dissolved from rGO@ Fe x P/C after the reaction is only 3.37% of bare Fe x P/C (14.6 mg L −1 ), while rGO@Fe x P/C achieves better performance towards sulfamethoxazole (10 mg L −1 ) degradation than Fe x P/C. Investigation on rGO@Fe x P/C with different thicknesses of outer rGO layer and diverse morphologic structures demonstrate that the unique structure of rGO@Fe x P/C played a decisive role in the simultaneously enhanced activity and stability.

“…Efficient removal of fluoxetine was observed by authors and the enhancement of catalytic activity was confirmed by comparing with natural pyrite and Fe salt. Ye et al [ 83 ] also evaluated the use of nano-ZVI@C and nano-ZVI@C-N obtained from MIL(Fe)-88B and NH 2 -MIL(Fe)-88B, respectively, to evaluate the effect of functional group. The nano-ZVI@C-N showed highest electrolytic activity with superior pollutant removal (57 and 90% removal after 60 min for ZVI@C and ZVI@C-N, respectively).…”

Metal–organic-frameworks (MOFs) are emerging materials used in the environmental electrochemistry community for Faradaic and non-Faradaic water remediation technologies. It has been concluded that MOF-based materials show improvement in performance compared to traditional (non-)faradaic materials. In particular, this review outlines MOF synthesis and their application in the fields of electron- and photoelectron-Fenton degradation reactions, photoelectrocatalytic degradations, and capacitive deionization physical separations. This work overviews the main electrode materials used for the different environmental remediation processes, discusses the main performance enhancements achieved via the utilization of MOFs compared to traditional materials, and provides perspective and insights for the further development of the utilization of MOF-derived materials in electrified water treatment.

1-Butyl-3-vinylimidazolium chloride was synthesized and polymerized with acrylamide to furnish an ionic liquid-containing polymer, which was then used for the formation of a composite with iron-based metal-organic framework. The resultant composite was characterized with XRD, TGA, FE-SEM, FTIR, EDS and elemental mapping analyses and its catalytic activity was appraised for ultrasonic-assisted Knoevenagel condensation. The results confirmed that the prepared composite could promote the reaction efficiently to furnish the corresponding products in high yields in very short reaction times. Moreover, the composite exhibited high recyclability up to six runs. It was also established that the activity of the composite was higher compared to pristine metal-organic framework or polymer.
