Conversion of Lignin Models by Photoredox Catalysis
ChemSusChem, 2018 AbstractOne prominent goal of 21st century research is to develop a sustainable carbon‐neutral biorefinery. Lignin is an important component of lignocellulosic biomass; however, it is currently underutilized owing to its highly cross‐linked, complex, and randomly polymerized composition, which poses a significant challenge to its depolymerization and ...
