Rh@N–SiO2 was stable except a little red shift which might
be caused by the increase of the bonding energy between the
CO and Rh over the rising of desorption temperature [32].

4 Conclusions
In conclusion, we developed a highly efcient Rh@N–SiO2
catalyst for formaldehyde hydroformylation reactionPleas.
Relative to pristine SiO2, the modifed N–SiO2 by APTES
grafting signifcantly elevated the unit Rh efciency and
the yielding of glycolaldehyde. We demonstrated that the
superior performance of this catalyst could be attributed to
the enhanced electronic metal–support interactions by Rh–N
bonding. We hope that the insight into the grafting method
for catalyst preparation will give researchers some clues for
the rational design of heterogeneous catalysts for hydrofor-
mylation reaction.
