Biomass
has attracted significant attention
as a carbon-neutral resource with the potential to reduce the vast quantity of
CO₂ emissions. Recently, the biomass-derived compounds such as
glycerol, furfural, and levulinic acid are identified as the best suited
alternatives for petroleum-derived chemicals. From the stand point of green
sustainable chemistry, development of highly selective and efficient catalytic
transformation of the above compounds has been desired.

We have developed novel
nanostructured heterogeneous catalysts capable of cooperative activation by
several active species using inorganic crystallites as unique macro ligands. We report here the
precise design of heterogeneous metal catalysts for highly selective
transformation of glycerol,^1-5 furfural,⁶ and levulinic
acid ^7,8 into value added chemicals. For example, highly selective
hydrogenolysis of glycerol to 1,3-propanediol could be catalyzed by Pt-WO_x
supported on aluminum oxide. The combination catalyst system using the lanthanum-exchanged
montmorillonite and the aluminum oxide-embedded Cu nanoparticles enabled
one-pot transformation of glycerol to 1,3-diacetoxyacetone via the acetylation,
oxidation, isomerization, and hydrogenation. Furthermore, the Pt nanoparticles
supported on hydrotalcite and Pt-MoO_x on hydroxyapatite selectively
converted furfural and levulinic acid into 1,2-pentanediol and 1,4-pentandiol,
respectively. The unique activities of the above nanostructured heterogeneous
catalysts will be also discussed.
