Pure silica mesoporous molecular sieves MCM-41 and MCM-48 organofunctionalized with 3-aminopropyltrimethoxysilane and N-[(3-trimethoxysilyl)propyl]ethylene-diamine, respectively, were served as supports to immobilize CuCl2 with conventional impregnation method. The supported copper catalysts showed a considerable enhancement in the reaction rate in heterogeneous vapor-phase oxidative carbonylation of methanol to produce dimethyl carbonate in comparison with that obtained by CuCl2-supported nonfunctionalized mesoporous silicas under identical conditions. The electronic donation of the amino groups, the accessibility and dischargeability of reactants in the regular mesopores probably account for the good catalytic performance as evidenced by the characteristic studies with XRD, BET, FTIR, TG-DTA, and XPS.

Non-porous fumed-silica nanoparticles were used as supports for the first time to immobilize water-soluble complex HRh(CO)(P(m-C6H4SO3Na)3 (1) [P(m-C6H4SO3Na)3, i.e. trisodium salt of tri-(m-sulfophenyl)-phosphine, TPPTS] to obtain supported aqueous-phase catalysts (SAPC) (fumed-SiO2-SAPC) for hydroformylation of 1-hexene. The experimental results proved that the structure of support and the support hydration were the determining factors contributing to the hydroformylation performance. The fumed-SiO2-SAPC where the water-soluble rhodium complexes were well dispersed onto the external surface of the silica nanoparticles presented a higher hydroformylation performance over a relatively wider range of support hydration as compared to the SAPC with conventional porous granular-SiO2 support (porous SiO2-SAPC). A positive effect on the reaction performance was observed from the particle size and surface area of the fumed-silica nanoparticles. The hydroformylation performance with fumed-SiO2-SAPC was promoted by an addition of basic alkali metal salts such as Na2CO3, K2CO3, and NaH2PO4, which depressed the oxidation of ligand TPPTS to OTPPTS [OTPPTS, i.e. trisodium salt of tri-(m-sulfophenyl)-phosphine oxide, OP(m-C6H4SO3Na)3] as evidenced by 31P NMR observation.

The solution NMR (31P and 1H) and FTIR spectroscopies were employed to investigate the structure information of water-soluble complex HRh(CO)[P(m-C6H4SO3Na)3]3 (1) [P(m-C6H4SO3Na)3: trisodium salt of tri-(m-sulfophenyl)-phosphine, TPPTS] supported on SiO2 (1/SiO2). The 31P(1H) NMR spectra showed that a pair of new twin-peak at about 31.5, 32.1 ppm while no typical twin-peak at 44.0, 44.7 ppm for the phosphorus species ascribed to the complex 1 were observed at 1/SiO2. However, the typical phosphorus peaks for the complex 1 appeared in the case of using TPPTS or Na2CO3-preimpregnated SiO2 as supports. Moreover, the immobilization caused a considerable oxidation of the liberated TPPTS to OTPPTS (OTPPTS, i.e. OP(m-C6H4SO3Na)3: trisodium salt of tri-(m-sulfophenyl)-phosphine oxide) species as evidenced by 31P(1H) NMR spectroscopy. The phosphorus-31 peaks at 31.5, 32.1 ppm at 1/SiO2 were found to be unchanged before and after the propene hydroformylation. The FTIR results revealed that the CO band appeared at about 1870 cm−1 for the 1/SiO2 catalyst, whichwas lower than that for the precursor complex 1. It is concluded that there exists a strong interaction between the complex 1 and the acidic support of SiO2, resulting in the deformation of the Rh-phosphine complex containing less than three TPPTS ligands, which further transformed by dehydrogenation and dimerization under evacuation to form a species likely [Rh(CO)(TPPTS)2]2 as a main surface complex species at the catalyst 1/SiO2.©2002 Elsevier Science B.V.

Structures and catalytic properties of a SiO2-supp0rted [Au6Pt] cluster, [(AuPPh3)6Pt(PPh3)](NO3)2 (1), were character-ized by FT-IR, in-situ EXAFS, and TPR, and also by the reactions such as H2-D2 equilibration, ethene hydrogenation, and CO oxidation to get insight into the key issues of metal catalysis. The cluster 1 was supported on SiO2 without fragmentation of the cluster framework at room temperature under Ar atmosphere. The cluster framework of 1/SiO2 was stable up to 400 K under vacuum. EXAFS analysis revealed that after heat-treatment of 1/SiO2 at 473 K under vacuum the coordination numbers of Pt-Au and Au-Au(Pt) decreased compared to those for the original clusters due to cluster deformation and after treatment of 1/SiO2 at 773 K the Au particles and Pt-P# species (P#: phosphine species) were produced. The combination of TPR and EXAFS showed that the reduction at 603 K caused complete cleavage of Pt-Au and Au-P# bonds accompanied with the formation of Au particles, While Pt-P# bonds remained at 773 K. The incipient 1/SiO2 showed catalytic activity in Ha-Da and ethene hydrogenation at 303 K without change of the cluster framework. The catalysis of 1/SiO2 was suggested to be referred to the platinum atom which was embedded in the six gold cluster by the results of CO-adsorption, EXAFS, and pulse reaction analysis. This is contrasted to the fact that both Pt(PPh3)4/SiO: and [Aug(PPh3)s](NO3)3/SiO2 showed no catalytic activity for these reactions.

mperatures 203–273 K, whereas 1/Fe2O3 and 1/TiO2 prepared by supporting 1 on conventional Fe2O3 and TiO2 showed negligible activity under the similar reaction conditions. It was estimated by TEMandXRDthat the mean diameter of Au particles in 1/Fe(OH)*3 was about 2.9 nm, which was about 10 times smaller than that for 1/Fe2O3. EXAFS for 1/Ti(OH)¤4 revealed that the coordination number of Au–Au bond was 8-10, while that for 1/TiO2 was 11.0, which also indicates that Au particle size for 1/Ti(OH)¤4 is smaller than that for 1/TiO2. The catalysts obtained by attaching the Au complexes on commercially available metal hydroxides also showed negligible activity for the low-temperature CO oxidation under identical conditions. These results demonstrate that supported Au catalysts with smallAuparticles, tremendously active for the low-temperatureCO oxidation, can be prepared by attaching the Au phosphine complexes on the as-precipitated metal hydroxides. Sodium cations exhibited positive effect on the Au catalysis, whereas chloride anions drastically decreased the CO oxidation activity.
