Electrochemical oxygen transfer reactions: electrode materials, surface processes, kinetic models, linear free energy correlations, and perspectives

摘要: This work summarizes progresses achieved in electrochemical oxygen transfer reactions from water to organic pollutant molecules on metal oxide electrodes during the past two decades. Fundamental understanding of dynamics reaction is crucial importance for development key concepts electrocatalytic processes, leading implementation environmental electrochemistry wastewater treatment schemes with rational design suitable systems. We discuss current knowledge reaction, emphasizing surface processes order generalize mechanistically experimental results obtained different electrode materials, describing also practical kinetic models developed and their implications. From information gathered this review, it apparent that explanations kinetics relation structure compounds involved lacking, hence new about structure-reactivity relationships needed. show particular open circuit decay concentration radical cations, spectroelectrochemical data, allows correlating adsorbed states reactivity reactions, pointing as well research efforts required understand catalytic performance decomposing strongly surfaces. Finally, some perspectives future area are briefly commented.
