Biomass-derived N-doped porous two-dimensional carbon nanosheets supported ruthenium as effective catalysts for the selective hydrogenation of quinolines under mild conditions

摘要

Biomass-derived N-doped porous two-dimensional carbon nanosheets (NPCNs) with high surface area and pore volume were fabricated by using graphitic carbon nitride (g-C3N4) as both template and nitrogen source. The NPCNs were found to be promising supports to immobilize Ru nanoparticles (Ru/NPCNs), and Ru/NPCNs exhibit excellent catalytic performance for quinoline hydrogenation. 98.3% conversion and 96.1% selectivity were obtained within 3.5 h at 40 degrees C and 1 MPa H-2, which is far better than traditionally materials supported Ru catalysts. This work may provide a new choice for the synthesis of porous two-dimensional carbon nanosheets that can be used as catalyst support.
