Fig. 4 Reuse of Pd/NbOPO4 together with TfOH for the one-pot
production of 1-octanol from FFA. The reaction was hydrogenated at
room temperature and 2.5 MPa for 3 h first and then reacted at 190 °C
for another 18 h.

Conclusions
In summary, we have demonstrated an energy-efficient cata-
lytic system for the one-pot production of 1-octanol from
biomass-derived FFA in water, by sequential hydrogenation/

hydrogenolysis using
a hydrophilic Pd/NbOPO4 catalyst
together with an acidic additive. Up to 62.7% yield of 1-octanol
was obtained under the optimal conditions over Pd/NbOPO4
together with TfOH as an acidic additive. The approach of
creating an intentional “phase problem” by using a hydro-
philic catalyst in water is proved to be able to prevent the over-
hydrogenolysis of 1-octanol, as 1-octanol would separate spon-
taneously from water once generated during the reaction due
to their immiscibility, which makes this catalytic system much
more energy-efficient for the industrial production. This
approach provides a new strategy to enhance the selectivity of
the target products by phase separation, for reactions whose
reactants are solvent-soluble but target products are solvent-
insoluble, particularly for medium- and long-chain primary
alcohol production from biomass-derived oxygenates in water.
