Abstract:

Considering the facts of fossil fuel depletion and environmental issues, the conversion of biomass into high valueadded chemicals is of great importance. In this work, Ni and Co were encapsulated in lignin-derived phenolic resin spheres to obtain NiCo@LRS, which was then employed as a sacrificial template for the synthesis of the bimetallic catalyst NiCo@LC-RS. The Ni and Co act as the acid and dehydrogenation sites for the catalytic transfer hydrogenolysis of 2-phenoxy-1-phenylethanol (pp-ol) and corncob lignin, respectively, and exhibit a synergistic enhancement effect. Under the optimal conditions of 170 degrees C, 1 MPa N2 and 4 h, the conversion of ppol reached 99.9 %, with the yields of cyclohexanol and ethylbenzene at 99.9 % and 93.8 %, respectively. The lignin was completely converted and the selectivity of monophenols was 55.74 %. The catalyst remained stable and reusable after 5 cycles. Furthermore, lignin oil can be employed in the preparation of Ni-Co bimetallic catalysts, which have been demonstrated to exhibit excellent catalytic properties. This work provides practical guidance for the high-value utilisation of lignin.
