“…The redox couples with different oxidation states serve as conduits for electron transfer, enabling electrons flow into halogenated organic compounds. [107][108][109][110][111][112][113] Chen et al 114 employed ZnCl 2 as the media to facilitate the electrocatalytic reduction of PCP. It indicated that the electrocatalytic mechanism of PCP reduction predominantly follows an indirect electroreduction pathway involving Zn/Zn 2þ as the redox media.…”

Electrocatalytic dehalogenation technology is a promising approach for the synthesis of chemicals (such as pesticides and pharmaceutical intermediates) and the disposal of halogenated organic pollutants. Compared with the traditional chemical reduction technology, the electrocatalytic reduction dehalogenation method has the advantages of high efficiency, controllable operation, and reduced secondary pollution. This review systematically consolidates the recent advances in the electrocatalytic dehalogenation in the application of organic synthesis and environmental degradation, focusing on the involved mechanisms, and influences factors (e.g., electrocatalysts, solution environment, and reaction conditions) on the performance of electrocatalytic dehalogenation. Furthermore, the latest characterization and analytical methods and the industrial application of electrocatalytic dehalogenation technology are summarized. Lastly, the existing challenges and perspectives are proposed for efficient electrocatalytic dehalogenation.

“…A number of transition metal macrocycles have shown promise in catalytic reductive dehalogenation, an important transformation to degrade many common water pollutants. Cobalt macrocycles, including cobalt phthalocyanines and cobaloximes, , have shown promise in electrocatalytically reducing chlorinated compounds. Cobalt and iron porphyrins immobilized on TiO 2 nanoparticles make use of favorable interfacial kinetics to support multiple electron transfer and enable photocatalytic C–Cl bond breaking following visible-light excitation. − Recognizing that these examples are productive toward carbon–halogen bond breaking, these molecular catalysts may be a good place to look for developing treatment systems for the degradation of particularly challenging per- and polyfluoroalkyl substances (PFAS) pollutants.…”

Advanced Materials for Energy-Water Systems: The Central Role of Water/Solid Interfaces in Adsorption, Reactivity, and Transport

et al. 2021

The structure, chemistry, and charge of interfaces between materials and aqueous fluids play a central role in determining properties and performance of numerous water systems. Sensors, membranes, sorbents, and heterogeneous catalysts almost uniformly rely on specific interactions between their surfaces and components dissolved or suspended in the waterand often the water molecules themselvesto detect and mitigate contaminants. Deleterious processes in these systems such as fouling, scaling (inorganic deposits), and corrosion are also governed by interfacial phenomena. Despite the importance of these interfaces, much remains to be learned about their multiscale interactions. Developing a deeper understanding of the molecular-and mesoscale phenomena at water/solid interfaces will be essential to driving innovation to address grand challenges in supplying sufficient fit-for-purpose water in the future. In this Review, we examine the current state of knowledge surrounding adsorption, reactivity, and transport in several key classes of water/solid interfaces, drawing on a synergistic combination of theory, simulation, and experiments, and provide an outlook for prioritizing strategic research directions.

“…[11][12][13][14][15] Based on the similar structure with vitamin B 12 , metalloporphyrinoids can also be used as efficient catalysts for the C-Cl bond cleavage of environmentally harmful organochloride through an electrocatalytic reduction process. [16][17][18][19][20][21] An in-depth study of the mechanism has demonstrated that the first step is a dissociative electron transfer from the reduced metal-center to the organochloride, leading to chloride elimination and the formation of a radical species. The re-oxidized metal complexes can then be re-used for the next catalytic cycle.…”

An electrochemically reduced Co(I) meso-tetraphenylporphyrin anion was examined in electron reductive dechlorination of environmental harmful organochlorides by using various supporting electrolytes. The tunable reactivities were formed when different supporting electrolytes were tested. For the first time the experimental and mechanistic investigations were combined, what provided useful information for future rational molecular design towards highly efficient removal of environmental harmful organochloride catalyzed by metalloporphyrins.
