Transitioning from crude oil to renewable sources of carbon-based chemicals is critical for advancing sustainable development. Lignin, a wood-derived biomacromolecule, holds great potential as feedstock, but efficient depolymerization and dearomatization methods are required fully unlock its potential. In this investigation, we present silver-catalyzed aqueous electrocatalytic method the selective partial soda lignin under mild, ambient conditions. Utilizing water/sodium carbonate solvent system silver electrode mediate electrochemical reduction, achieved significant over reaction times ranging 5 20 h. Analysis by nuclear magnetic resonance (NMR) high-resolution mass spectrometry (HRMS) revealed sodium levulinate, acetate, formate main aliphatic products, alongside various aromatic species in depolymerized products (DL). This conversion into both valuable compounds reactive intermediates offers promising opportunities further synthesis wide range organic chemicals, contributing development more circular economy.
