A strategy has now been created to immobilize non-noble metal particles on supports using metal–organic frameworks (MOFs) as precursors. Ni/C-X and other metal-based catalysts were synthesized using trimesic acid as ligand to transform lignin dimer and lignin to obtain high value-added fuels or chemicals (benzoic acid and phenol). Then, a mild Ni-based catalytic oxidation system under O2 atmosphere was established. The introduction of Ni enhanced the strong acid sites of the spherical MOF catalyst, and the synergistic effect between the Ni and carbon support greatly improved the catalytic activity. Under optimal catalytic conditions, Ni/C-10 catalyst could break the β-O-4 bond in lignin dimer under 160 °C for the production of benzoic acid and phenols. In addition, Ni/C-10 catalyst also showed excellent desulfurization ability in the oxidation depolymerization of lignosulfonate.
