Ru Nanoparticles on a Sulfonated Carbon Layer Coated SBA-15 for Catalytic Hydrogenation of…
Fig. S11, the recycling test could not infuence the ordered
mesoporous structure of the Ru catalyst. Meantime, the
sulfonic acid density of the reused catalyst was determined
quantitatively by the titration method (Table 1), it was found
that even after six catalytic recycles, the sulfonic acidity
of the catalyst showed a negligible loss and remained at
0.22 mmol·g−1. It suggested that a sulfonated carbon layer
coated SBA-15 was highly water-resistant and the dispersed
Ru species was robust for the catalytic hydrogenation likely
via a coordination with a sulfonic groups.
of other biomass molecules, thus opening up a new route
to produce high-value-added chemicals directly from FFR.

Finally, the catalytic performance of the present system
was compared with the other earlier reports for the hydro-
genation of furfural into 1,4-PeDO. As shown in Table S3,
the present bi-functional catalyst can aford the comparable
or higher yield of 1,4-PeDO to that of the reported systems.
Notably, the present catalytic system was able to catalyze
the reaction under milder conditions (short reaction time
and low H2 pressure). Besides, the present catalyst is simple
and can be easily available by a conventional method. Mean-
time, it was highly stable in consecutive catalytic recycles.
Inspired by the above results, the design of more-efcient
bi-functional catalysts for the catalytic direct conversion of
FFR to high-value-added chemicals with high stability is
currently underway in our laboratory.

In summary, the highly efcient metal–acid bi-functional
catalyst has been prepared by using the carbon layer coated
C/SBA-15 as a catalyst support, which was then sulfonated
with 98% concentrated sulfuric acid, followed by incorpo-
ration Ru species. This approach has an advantage in that
the acid density was tuned fexibly via controlling sulfonat-
ing time. The resulting Ru/SC-SBA-15_6h catalyst have
exhibited an excellent catalytic activity (with full conver-
sion of FFR) and high yield of 1,4-PeDO (87%) in selective
hydrogenation of FFR under the optimum condition. The
detailed characterization demonstrated that both the sulfonic
acid group and highly dispersed Ru sites are very crucial for
achieving high yield of 1,4-PeDO. Notably, there was a coor-
dination interaction between the sulfonic acid groups and the
adjacent Ru sites, which endowed Ru sites with high elec-
tron density. The electron-rich Ru sites promoted H2 disso-
ciation and were benefcial for a sequential hydrogenation of
the ring-opining intermediates by acid-hydrolysis. Moreover,
such a bi-functional catalyst also exhibited excellent dura-
bility. The surface acid density and the ordered mesoporous
structure on the catalyst remained no obvious change even
after at least six catalytic recycles. The present strategy of
introducing Ru species on a sulfonated carbon layer coated
SBA-15 to modulate the acidity and metallic bifunctional-
ity of the catalysts could be extended to the transformation
