Trends in Research on Electrochemical Oxidation

Abstract

Abstract. This paper presented a detailed chronological survey of scientific output related to electrochemical oxidation in SCI categories of "environmental sciences, environmental engineering and water resources" from 1975 to 2012. Publications were analyzed by distribution of the number of publications and times cited, source categories, source journals, author keywords, KeyWords Plus, and the most cited publications in these years. It was concluded that Pt, boron-doped diamond, TiO 2 were currently and would continue to be the predominant focused electrode materials at least over the next decade. And the foci of studied pollutants in the electrochemical oxidation were mainly concentrated in dyes and phenols popularly existing in the practical wastewaters. What's more, electrochemical degradation, wastewater treatment, electrochemical determination and fuel cell would be the key research topics currently and recently. Fenton, photocatalysis and coagulation were the most-frequent combination technology with electrochemical oxidation based on the bibliometric results. Contribution of Croatian chemists to the field is mentioned.

Modeling and optimizing an electrochemical oxidation process using artificial neural network, genetic algorithm and particle swarm optimization

“…Electrochemical oxidation (EO) is one of the most promising advanced oxidation processes (AOPs) that has been widely used for the treatment of industrial wastewater, contaminated groundwater, and hazardous waste due to its energy efficiency, usefulness, and environmental friendliness. [1][2][3][4][5] Via EO, a large number of active substances (mainly hydroxyl radicals, • OH) are produced, which can both directly and indiscriminately react with contaminants, and mineralize pollutants into CO 2 , H 2 O, or simple intermediates without secondary pollution. [6][7][8] Therefore, the application of electrochemical technologies can provide an alternative to treat wastewaters containing biological toxicity and resistant substances, which conventional methods cannot properly dispose of (e.g., pharmaceutical wastewater, industrial dye wastewater, or municipal solid waste leachate).…”

Transformation of chlorobenzene and 4-chlorophenol in groundwater by electro-fenton and sono-electro-fenton reactions

“…The concept involves the electrochemical oxidation process as a source of generating strong oxidants and is similar to chemical destruction. The versatility, environmental compatibility, energy efficiency and amenability to automation are some benefits of this technique (Yuan, Chen et al 2013, Yuan, Gou et al 2013b, Li, Shi et al 2014. In other words, electrochemical oxidation is distinctive by three features.…”
