The instability of heterogeneous catalysts would restrict their
catalytic applications; therefore, the stability and recyclability of
as-prepared catalysts were examined by consecutive runs
reactions, SEM, TEM, and PXRD (Figure S2a, S2b S5a and
S5b).[8g] Firstly, the recyclability experiment was performed
under the same conditions by recycling catalyst after separated
by centrifugation and washed with ethanol. Figure S2a exhibits
that the selectivity and conversion of Pt/MOL are maintained
after five consecutive runs without any activity loss. In addition,
the Pt NPs loaded in the MOL were not obviously aggregated
after at least five runs reactions as demonstrated by SEM and
TEM (Figure S5a and 2b). The PXRD patterns proved the
structures are retained after reactions and the Pt NPs are well
dispersed as evidenced by the short and broad peak at 39.4
degree (Figure S5b).[9c] ICP result was also indicative of no
detectable leaching of Pt during the reaction. The excellent
recyclability may result from that MOL has the ordered pores
and strong interaction originated from the BPYDC ligand, which
can confine and well disperse the Pt NPs.

In summary, we for the first time combine the two
hydrogenation mechanism: transfer and catalytic hydrogenation
to achieve high regulation of the hydrogenation selectivity of α,β-
unsaturated aldehydes. Through transfer hydrogenation with
ammonia borane, unsaturated alcohols can be exclusively
produced and the saturated alcohols can be selectively
synthesized by synergistic action of ammonia borane and Pt-
loaded metal-organic layer, the latter of which simultaneously
dehydrogenate ammonia borane and hydrogenate the C=C
bonds. The combination of two hydrogenation mechanism not
only can highly regulate the chemoselectivity of hydrogenation
reactions but also avoid the usage of external hydrogen
atmosphere. The strategy can be extended to various α,β-
unsaturated aldehydes and the catalysts can be recycled for
several times without any loss of activity. Unfortunately, only two
hydrogenation products could be synthesized in this work.
Controllable regulation of three hydrogenation products of α,β-
unsaturated aldehydes would be a big challenge and more
important, which might be achievable by elaborate design of
MOF-based catalysts. We envision that this mild approach
would open an avenue for hydrogenation of α,β-unsaturated
aldehydes to replace the traditional rigorous methods and the
combined strategy would be extendable to other systems, where
high regulation of selectivity is required.
