| Abstract | Replacing fossil resources as the primary source of carbon-based chemicals by alternative feedstocks, while implementing more sustainable production routes, has become imperative for environmental and resource sustainability. In this context, lignin, often treated as a biomass waste, emerges as an appealing candidate, considering the principles of circular economy. For this pursuit, depolymerization methods offer potential strategies to harness lignin to produce valuable organic chemicals, while electrocatalysis processes stand out especially in the context of sustainability, as they can be powered by electricity from renewable sources. This minireview article explores the pivotal role of various electrocatalysts in lignin depolymerization, investigating both oxidative and reductive pathways. Emphasizing recent advancements, the review delves into the diverse nature of electrocatalysts and their influence on lignin valorization. Highlighting current trends, the discussion encompasses the catalytic mechanisms and selectivity of electrochemical processes employed for lignin breakdown. Additionally, some insights into emerging technologies are also offered, emphasizing the need for sustainable and efficient strategies. By providing an overview of the field, this minireview aims to guide future research endeavors toward innovative electrocatalytic approaches for lignin depolymerization, paving the way for sustainable biorefinery processes. |
