  "abstract": "Lignin valorization remains a critical challenge due to its heterogeneous and recalcitrant nature, which complicates conversion into value-added chemicals. While conventional thermochemical methods rely on harsh conditions that compromise biorefinery economics, lignin’s solubility—dictated by its isolation method—further hinders efficient processing. Here, we report a one-pot electrooxidative depolymerization strategy for propionaldehyde-stabilized lignin (PA-lignin) using nickel electrodes in alkaline media. This approach selectively cleaves ~24 % of the lignin polymer into aromatic monomers, predominantly syringyl and guaiacyl derivatives, under mild conditions and without redox mediators. Compared to unmodified lignin, PA-lignin yields 28% ethyl acetate-extractable products, nearly fourfold higher, demonstrating that propionaldehyde capping suppresses condensation reactions and enhances monomer release. The simplicity of this single-step electrochemical process, combined with its improved monomer yield, makes it a promising and scalable upgrade for future lignocellulosic biorefineries.",
