Lignin (an aromatic macromolecule in biomass), the only renewable source of aromatics, is currently treated as waste and under-utilized. A more appealing and value-added use of lignin is as a ...

Lignin is an abundant renewable resource, but its intrinsic recalcitrant nature has so far hampered its conversion into higher value chemicals. Now, a two-step strategy, oxidation followed by bond ...

Now, scientists have built upon recent lignin depolymerization methods to introduce a green, efficient, three-step pathway from lignin to bioactive compounds that can be turned into drugs (ACS ...

A recent review examines the latest trends in the depolymerization of lignin model compounds, focusing on catalytic systems that could revolutionize the sustainable chemical industry.

The researchers further stated, “Our results showed that these peptoid-based enzyme mimetics can catalyze the oxidative depolymerization of organosolv lignin under much milder conditions with a ...

Lignin in plant cell walls can be broken down into component polymers that ... The findings indicate that the ability to form those interactions is important for enabling lignin depolymerization.

Leem and Yoo will study how a dye-sensitized photoanode can chemoselectively oxidize lignin with a suitable catalyst as a first step toward a solar or visible light-driven lignin depolymerization ...

Structural Evolution of Lignin Using In Situ Small-Angle Neutron Scattering during Catalytic Disassembly. ACS Sustainable Chemistry & Engineering , 2024; 12 (6): 2241 DOI: 10.1021/acssuschemeng ...

In addition to Niu and Wang, additional co-authors of the report– titled “Photocatalytic Depolymerization of Native Lignin Toward Chemically Recyclable Polymer Networks” – include graduate students ...

Although lignin depolymerization has been studied for nearly a century, the development of cost-effective upgrading processes for lignin valorization has been limited.
