Hydrogenolysis of lignosulfonate into phenols over heterogeneous nickel catalysts

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 naturally abundant element, and is recyclable and reusable.
