Enhanced selectivity of reactive intermediates by modifying electrodes with layered materials for the green high-salinity wastewater treatment
Improving the selectivity of the reactive intermediates such as and by modifying nickel foam electrodes with ion exchangeable layered materials would greatly enhance the efficiency of high-salinity wastewater treatment. A universal pattern was verified herein that through functioning as a permeable overlayer regulating the transport of cations/anions, and could be the predominant intermediates in the anionic/cationic layered material modified electrode. The significance of selectivity enhancement includes improving electrochemical efficiency and reducing the usage of chemical reagents. For instance, it is demonstrated that electrochemically degrading high salinity azo wastewater using decorated electrodes would be as effective as chemical treatment. Furthermore, electrochemical oxidation using cation layered material modified electrode could reduce the pKa of the oxidized cellulose filter paper as effectively as using .
期刊介绍:
The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice.
PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers.
PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
