One of the central challenges for biomass utilization is the selective, catalytic hydrogenolysis of C–O bonds. 1–4 Hydrogenolysis will play a central role in future biorefineries, both for the production of value-added chemicals 5–7 and for the depolymerisation of raw biomass 8–10 such as lignin. 11 Indeed, the hydrogenolysis of lignin is an attractive route, among others, 12–18 to transform the world's most abundant aromatic polymer into energy carriers and ...
