Nickel nanoparticles inlaid in lignin-derived carbon as high effective catalyst for lignin depolymerization
Ni nanoparticles inlaid in lignin-derived carbon constructing the ?inlaid type? Ni/C-I was reported to improve stability and adjust metal-support interaction of lignin hydrogenolysis catalyst. The Ni/C-I was further heat treated in air to prepare Ni/C-R so as to re-expose the blocked active sites by carbon species. A lot of characterization techniques were carried out to confirm the ?inlaid structure? of the catalysts. The lignin depolymerization results demonstrated that the Ni/C-R had better catalytic performance than traditional ?supported type? Ni/C, 23.3% aromatic monomer yield and 82.4% bio-oil yield were achieved. Moreover, the mechanism studies with lignin model compound revealed that Ni/C-R had better bond breaking ability than Ni/C, even C[sbnd]C bond could be cleaved. The electron effect could be responsible for that, since the electrons could transfer from Ni0 to carbon support for Ni/C-R, which could improve the bond breaking ability.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 3-Hydroxytetrahydrofuran, you can also check out more blogs about453-20-3
