on the silica support and have H2 reduction and desorption
properties completely different from those of Co3O4/SiO2 or
Co/SiO2. The CoSi/SiO2 sample showed a catalytic activity
and selectivity to tetralin superior to those of a Co/SiO2
catalyst in the hydrogenation of naphthalene. The results
indicate that metal silicides are novel promising catalysts in
the hydrogenation of aromatics and may find application in
petroleum processes and in the synthesis of fine chemicals.

of highly dispersed CoSi on silica, which is totally different
from the Co/SiO2 sample.
The hydrogenation activities of CoSi/SiO2 and Co/SiO2
catalysts were tested in the hydrogenation of naphthalene at
340 1C and 4.0 MPa. The passivated catalysts (0.2 g, diluted
with 2.0 g SiC) were activated in situ with H2 at 400 1C and
0.1 MPa for 4 h. The reaction was carried out in a continuous
fixed-bed reactor. The liquid reactant was composed of
1 mol% undecane (as internal standard for GC analysis),
5 mol% naphthalene reactant, and varying amounts of decane
(as solvent). The reaction product was analyzed by off-line gas
chromatography with an OV-101 capillary column and a flame
ionization detector. Product identification was performed with
an Agilent 6890 gas chromatograph equipped with a HP-5MS
capillary column and an Agilent 5973 mass selective detector.
The hydrogenation of naphthalene over CoSi/SiO2 occurred
in two steps: the conversion to tetralin, followed by the
formation of decalin. The conversion of naphthalene increased
with an increase in contact time from 0 to 6.6 min (Fig. 4).
Among the three catalysts, the 13.5% CoSi/SiO2 showed the
highest conversion, which shows good consistency with the
H2-TPD results. The results can be explained by the size effect
of the CoSi particle and the interactions between CoSi and
SiO2. The selectivities of the products showed that naphthalene
hydrogenation to tetralin is the main reaction (100% selectivity
to tetralin) and further hydrogenation of tetralin did not take
place at a low contact time (3.76 min), indicating that the
hydrogenation of tetralin is a rate-controlled step over
the CoSi/SiO2. However, no product was detected over the
Co/SiO2 catalyst under the same reaction conditions. This
shows that the CoSi/SiO2 catalyst is much more active than
the Co/SiO2 catalyst. The results show that CoSi/SiO2 is a
promising catalyst for semihydrogenation, which can be very
important in the synthesis of fine chemicals.

In conclusion, highly dispersed CoSi particles on a silica
support have been synthesized by MOCVD of Co(SiCl3)(CO)4
as a precursor at atmospheric pressure and moderate temperature
in a fluidized bed reactor. The results show that the resulting
CoSi particles with a size of about 2 nm were highly dispersed
