Different lignosulfonate (LS) samples were prepared via a three-step method and were characterized by FT-IR, UV, GPC and functional groups measurement. FT-IR and UV spectra confirmed the prepared samples had typical characteristics of lignin materials. GPC and functional groups measurement

We report a strategy for the catalytic conversion of lignosulfonate into phenols over heterogeneous nickel catalysts. Aryl-alkyl bonds (C-O-C) and hydroxyl groups (-OH) are hydrogenated to phenols and alkanes, respectively, without disturbing the arenes. The catalyst is based on a
