Abstract
The conversion of glycerol to value-added products has received considerable attention recently because the booming biodiesel industry produces a large amount of glycerol as a byproduct. Among various means, electrocatalytic oxidation of glycerol is appealing owing to its environmental friendliness and high efficiency. However, electrooxidation of glycerol is very complex, involving multiple electron and proton transfer processes with many reaction pathways. How to rationally design catalysts with high selectivity toward targeted products is an overarching challenge, and of both fundamental and practical significance. In this minireview we aim to provide an overview of recent advancements in electrooxidation of glycerol focusing mainly on Pt- and Pd-based catalysts. We start with summarizing fundamental understandings of factors dictating catalytic activity and selectivity garnered fromin-situ and online spectrometric experimental studies as well as from theoretical works. We then use selective examples to demonstrate how these factors are manifested in the development of highly efficient glycerol electrooxidation catalysts. Finally, we summarize the key issues to be addressed in future studies.
