Catalytic Depolymerization of Alkali Lignin Using Supported Pt Nanoparticle Catalysts

J Nanosci Nanotechnol. 2016 May;16(5):4570-5. doi: 10.1166/jnn.2016.10982.

Abstract

Alkali lignin, a byproduct of the pulping process, was depolymerized using Pt nanoparticle catalysts. A depolymerized lignin with a lower molecular weight was obtained and characterized with GPC and NMR. 31P-NMR using OH-sensitive probing molecules showed the formation of guaiacyl OHs during the reaction, indicating the cleavage of guaiacyl ether bonds.
