The invention belongs to the technical field of metal solid catalysts, and specifically discloses a carbon-nitrogen material-supported nickel catalyst with adjustable mesopore pore diameter, a preparation method and application thereof. The invention adopts the hydrothermal synthesis process to pretreat the carbon source precursor and the template agent, and the template agent is well incorporated into the carbon carrier through the self-assembly process. The pore size of the synthesized nickel-based composite nitrogen-doped carbon material nanocatalyst carrier can be adjusted, the metal particles are small, the specific surface area is large, the dispersion is uniform, and there is no obvious agglomeration. The single benzene ring compounds can be efficiently prepared by depolymerizing lignin, the selectivity to propyl eugenol and propyl guaiacol is high, the catalyst cycle stability is high, and the yield of monophenol reaches 28.21%. |
