“…The highest relative contents (4.44% and 2.57%) were measured at 140MAC24 by semi-quantitative analysis [Supplementary Table 3 and Supplementary Figure 1]. Undoubtedly, the O/C atomic ratio (0.300) also reveals that 140MAC24 had the more active sites and abundance of oxygen-containing functional groups (OFGs) than other samples [42] . This result implied the eminent surface wettability and highly efficient electron transfer, consistent with the FTIR analysis mentioned above.…”

The low performance of electrode materials is the main obstacle limiting the development of the supercapacitor industry, which can be solved by doping cobalt ferrate nanoparticles (NPs) with carbon materials. Herein, the composites of CoFe2O4 based on activated carbon (AC) were successfully prepared using a one-step solvothermal method and subsequently applied in anodes of battery-type asymmetrical supercapacitors. The effect of solvothermal temperature and heating time on the composite characteristic was systematically evaluated. The electrochemical analysis in the three-electrode system revealed that modified activated carbon heated at 140 °C for 24 h (140MAC24) displayed excellent specific capacitance of 571.36 F/g at the current density of 0.2 A/g due to the synergistic effect of the double-layer and faradic capacitance. Moreover, iron and cobalt elements in CoFe2O4 could change into the oxide form to accelerate charge in potential range window of -1.0 to -0.2 V and discharge from -0.2 to 0.2 V, respectively. Meanwhile, the result of assessing economic feasibility suggested the splendid availability of 140MAC24 electrodes. Additionally, the assembled supercapacitor displayed the outstanding specific capacitance of 171.31 F/g in the potential window of 1.8 V, energy density of 43.5 Wh/kg at the current density of 0.2 A/g, and capacitance retention rate of 82.49% after 10,000 cycles. The excellent electrochemical properties demonstrated that CoFe2O4 could be used as a bifunctional agent for enhancing supercapacitive performance.

“…The dehalogenation of organic halides coupled with carboxylation at metal electrodes has shown good versatility, being applicable for a large variety of substrates. [33][34][35] Metal-based nanostructures are the most suitable cathode materials, often guaranteeing a good level of conversion selectivity into the corresponding carboxylic acids, occurring with high efficiencies. Pt nanoparticles (NPs) embedded into N-doped carbon/ carbon cloth (Pt-NP@NCNF@CC) prepared by the electrospinning technique could drive the electrocarboxylation of 1-phenylethyl bromide with CO 2 to yield the corresponding 2-phenylpropionic acid, a crucial intermediate for the synthesis of non-steroidal anti-inflammatory drugs, with an efficiency of 99% (entry 1 in Table 1).…”

“…The mechanisms of electrocatalytic reduction dehalogenation stems from the dissociative electron transfer (DET) theory. 60,86,96,97 Based on most of the previous research, three typical mechanisms for electrocatalytic reduction dehalogenation process are proposed, including direct electrocatalytic dehalogenation by electrons, electrocatalytic hydro-dehalogenation, and indirect electrocatalytic dehalogenation by media (Figure 4). In a specific reaction, these mechanisms can operate on independently or competitively.…”

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.
