WebApr 11, 2024 · Ralph’s group is recognized for their work on lignin biosynthesis, including delineation of the pathways of monolignol synthesis, lignin chemistry, and lignin reactions. He has also defined the chemical effects of perturbing lignin biosynthesis, and extensions of this work are aimed at redesigning lignins to be more readily degraded. WebElectrochemical oxidation of lignin has been widely regarded as a clean and reliable alternative to obtain value-added products from lignin, such as vanillin or guaiacol. This work aims to go one step beyond the production of low molecular weight molecules and explore the possibility of using lignin residues from electrochemical treatments in ...
WebLignin is the most abundant biopolymer with aromatic building blocks and its valorization to sustainable chemicals and fuels has extremely great potential to reduce the excessive … WebCleaving the C−C bonds in lignin to afford value-added low-molecular-weight aromatic products is promising but a challenging project. In this contribution, a mild and efficient strategy for one-step selective C−C bond cleavage in β-O-4 and β-1 lignin models has been developed over pyridinium-based photocatalysts.
