Mixed Cu-Mn Oxide Catalysts for Solvolysis of Technical Lignin.

ABSTRACT: With the rising demand for fuel and the societal shift toward sustainable resources, lignin emerges as a prime feedstock. Lignin is mainly composed of aromatic compounds linked within a complex matrix and holds significant potential as a source of renewable aromatics. Technical lignin, the most abundant form of lignin, is often degraded due to harsh biomass pretreatment processes. Cu₂₀MgAlO _x porous mixed oxide (CuPMO) is an efficient catalyst to help solvolyze technical lignin. Here, we demonstrate the promotion of such mixed oxides with Mn toward improving both the yield of monomers and solubilized lignin oil. The promotion was highest at a Cu/Mn ratio of unity, resulting in a 2-fold increase in monomer extraction compared to the benchmark CuPMO. The Mn-doped
