Conclusions
In conclusion, a nitrogen-doped carbon material with a high surface
area was successfully prepared from renewable biomass, and the
as-prepared nitrogen-doped carbon shows a strong ability to
anchor Pd nanoparticles with an ultra-small size of 1.9 nm. The
Pd/CN catalyst demonstrated a high activity for the hydrogenation
of quinolines to 1,2,3,4-tetrahydroquinolines under mild reaction
conditions. This method can promote the hydrogenation of
quinolines to afford the corresponding 1,2,3,4-tetrahydroquinolines
with high to excellent yields (86.6-98.0 %) under mild conditions (50
oC, and 20 bar H2) without the reduction of other functional groups.
More importantly, the Pd/CN catalyst was highly stable and can be
reused without the loss of its catalytic activity. The Pd/CN catalyst
shows a promising potential for the hydrogenation N-heteroarenes
into saturated N-heterocyclic compounds.
