Transition metal (Ti, Mo, Nb, W) nitride catalysts for lignin depolymerisation†
Abstract
Metal nitrides are promising catalysts for depolymerisation of lignin in supercritical ethanol; cheap and abundant titanium nitride affords an aromatic monomer yield of 19 wt% from soda lignin. The reaction mechanism is discussed on the basis of the products and a guaiacol model compound study.
