strongly than PA on the catalyst, thus occupying sites and reducing
the probability of adjacent PA–PA adsorption and reaction to 3-PN.
Even relatively low surface coverage of BA could therefore signifi-
cantly reduce PA ketonization rate, a concept that is supported by
the formation of 3-HX in quantities greater than 3-PN.

4. Conclusions
The citrate method has been used to generate active centers of
MnOx/CeO2 catalyst on two different types of mesoporous silica
supports (HMS and MCM-41). FTIR spectroscopy results suggest
that a metal–citrate complex is formed during the preparation of
CM-HMS and CM-MCM-41. This complex is decomposed during
the calcination step. FTIR results also show that MnOx/CeO2 is
incorporated to a small degree into the silica matrix framework
of HMS and MCM-41, but powder XRD, N2 adsorption, and diffuse
reflectance UV-vis studies reveal that most MnOx/CeO2 is present
as particles on the walls of silica pore network of HMS and
MCM-41, while the rest is highly dispersed on the surface of
HMS and MCM-41. The EDX analysis confirms the particles of
Mn and Ce are uniformly distributed over CM-HMS and CM-
MCM-41 catalyst. The supported CM-HMS and CM-MCM-41 cata-
lysts have better utilization of Ce and Mn than unsupported
MnOx/CeO2 for ketonization of propionic acid and butyric acid, be-
cause they are distributed on the mesoporous support. A more uni-
form dispersion of MnOx and CeO2 apparently forms on HMS and
MCM-41 than in the bulk catalyst, as evidenced by FTIR and UV-
vis spectroscopy. Thus, CM-HMS and CM-MCM-41 hold significant
promise as solid base catalysts to upgrade carboxylic acids to high-
er value intermediates or biofuel components.
