“…This methodology has been used by Roman-Martinez and collaborators since 2006 [365] for the immobilization of the Rhcomplex [Rh(COD)NH 2 (CH 2 ) 2 NH(CH 2 ) 3 Si(OCH 3 Table 16 entries 1-5) on the surface of AC [366], AC cloth [366], MWCNT [366,367], CNF [366,368,369] and CX [369,370]. Similarly, the amino-functionalization of graphite oxide with N-[3-(trimethoxysilyl)propyl]ethylenediamine was used by BachillerBaeza [371] and Fan [372] for the immobilization of ruthenium or palladium complexes, respectively (Table 16, entries 6-7).…”

“…However, the catalysts prepared with carbon nanotubes and carbon nanofibers show an exceptionally high activity, which was attributed to a confinement effect owing to the location of the metal complex in the few nanometers sized hollow cavity of these supports. [7][8][9] The work was extended using four multiwall carbon nanotubes of average inner diameter ranging from 4 to 10 nm as support. A clear effect of the inner cavity size of carbon nanotubes was observed.…”

Support effects in a Rh diamine complex heterogenized on carbon materials

2013

The Rh diamine complex, [Rh(COD)NH2(CH2)2NH(CH2)3Si(OCH3)3] BF4 has been heterogenized by covalent bonding on two carbon xerogels and on carbon nanofibers, with the objective of preparing hydrogenation hybrid catalysts. Gas adsorption, SEM, TEM, DTP, ICP-OES and XPS were used for characterization. The results indicate that the active molecule is mainly located in supermicropores and produces microporosity blockage. The hybrid catalysts are more active than the homogeneous complex, but the Rh complex is partially reduced upon reaction. This modification has been related with the nature of the support, which has also shown to have an effect in the stabilization against sintering of the Rh particles formed. The support porosity is behind differences in selectivity between the catalysts.

“…As previously reported [26][27][28], the anchoring on the support is assumed to occur through a covalent siloxane-type bond created by reaction of methoxy functions with surface -OH type groups. It has been found that catalysts prepared in this way on different carbon materials are, in general, more active than the Rh(NN)Si in homogeneous phase and they are reusable [26][27][28]. Therefore, it was decided to extend the study to two structured carbon-based supports such as the CNF-monolith described above and a granular carbon xerogel.…”
