Abstract
The conversion of biomass into carbon materials has become an essential pillar of sustainability in electrochemical technologies. However, biomass-derived carbons and their electrodes are complex materials. This opinion article raises concerns about the need to correlate physicochemical properties of these carbon materials with those of the biomass precursor, the electrode composition, and the electrode/electrolyte interface to rationalize the comprehension of their electrocatalytic performance. The electrocatalytic activity of biomass-derived carbons in aqueous environments is discussed for several reactions of interest in terms of the nature and stability of electroactive sites and the ability to form radicals. All these are strongly related to the characteristics of the carbon material (composition, type of functional groups, porosity, structural order) and the manufacture of those electrodes. Concerns are also raised about the ambiguities and misconceptions associated with the lack of consensual terminology on biomass-derived carbons. Finally, recommendations are presented when reporting the electrocatalytic activity of biomass-derived carbons; emphasis should be paid to demonstrate the reproducibility of biomass-derived carbon electrodes and their stability through long-term electrocatalytic assays.
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 •
