Abstract
Biodiesel, developed as an alternative to natural fossils, is produced by a transesterification reaction. The main co-product of this reaction is represented by glycerol, whose production in 2020 exceeded 6 times the current demand. A consequence of the spreading of biodiesel market was a drop of glycerol price. This versatile biomass-derived compound can be used as an important raw material for the manufacture of valuable chemicals including dihydroxyacetone (DHA), which is the most high-valued glycerol-derived product. Despite all the research devoted to achieve selective oxidation of the secondary alcohol group, this issue remains a scientific challenge. Among several routes for glycerol valorization, electrochemistry is an attractive process as discussed in this review. After a short introduction, which describes non-electrochemical methods, electrochemical oxidations on precious (based on Pt, Pd, Au and Ag) and non-precious metal electrocatalysts is discussed, with a specific focus on selectivity towards DHA.
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 •
