Catalytic
hydrodeoxygenation is of prime importance in
the valorization
of biomass-based feedstocks to produce essential chemicals and fuels.
To carry out this process in a more cost-effective and sustainable
manner, the use of 3D-metal-based nanostructured catalysts is highly
desired. Here, we report the preparation and application of Ni nanoparticles
supported on ZSM-5 (the Si/Al ratio is 80) as a general and efficient
hydrodeoxygenation catalyst. These Ni-based nanoparticles catalyze
the selective hydrodeoxygenation of a wide range of funcational substrates,
including ketones, ethers, and phenols, and also reduce aromatic rings
to produce (cyclo) alkanes. Notably, the hydrodeoxygenation of fatty
acid derived ketones to long-chain alkanes, lignin derived molecules,
and polyether ether ketone decomposition compounds to cyclohexane-based
products highlight the versatility of this novel Ni catalyst.
