Electrocatalysis of organics for electrolysis and/or fuel cells: Some thoughts on using the ratio of forward to backward peak current as a measure of electrocatalyst efficiency and/or poisoning
In the current context of sustainability, the selective electrocatalytic transformation of biomass-derived organic substances into value-added products should offer vast design possibilities for power generation or the electrosynthesis of fuels and commodity chemicals. In this contribution, we have examined a number of concepts concerning the electrocatalysis of organic molecules for which noble metals cannot be excluded from the electrocatalyst composition without compromising the significant energy savings promised in electrolyzers (up to 50 % for H2 co-production compared with conventional water electrolysis). The widespread practice of using the ratio of forward peak current to backward peak current as a measure of activity, anti-poison capacity or removal of adsorbed poisons or intermediates is unsuitable based on voltammetry and spectroelectrochemical analysis.
期刊介绍：
The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner:
1.The views of experts on current advances in electrochemistry in a clear and readable form.
2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.
In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle:
• Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
