α-Bi2Mo3O12, β-Bi2Mo2O9 , and γ-Bi2MoO6 as target bismuth molybdate phases were prepared by hydrothermal synthesis flame spray pyrolysis tested for their catalytic performance in the selective oxidation of propylene. Their structure reactivity during temperature-programmed reaction (TPR) under conditions investigated situ operando X-ray absorption spectroscopy (XAS), diffraction (XRD), Raman spectroscopy. To gain insight into amorphous crystalline structures at same time, XAS XRD well...
Herein we report the use of supported nanoparticles crystalline rhodium sulphides as active heterogeneous catalysts for hydroformylation alkenes showing an excellent selectivity towards aldehyde products. It was found that RhxSy (x=17, y=15 or x=2, y=3 with 1 and 10 wt.% Rh) greatly outperform pure Rh in terms activity, Rh17S15/SiO2 being superior catalyst candidate. The TOF styrene, determined lead system (1 Rh), is 2620 h-1 significantly higher than values reported phosphide-based systems....
The hydroformylation of alkenes is a cornerstone transformation for the chemical industry, central both functionalizing and extending carbon backbone an alkene. In our study, we explored silica-supported crystalline rhodium sulfide nanoparticles as heterogeneous catalysts in reactions, found that RhxSy systems (x=17, y=15 or x=2, y=3 with 1 wt.% Rh on SiO2) greatly outperform metallic nanoparticles. These proved to be exceptionally competitive when benchmarked against other cutting-edge...
Abstract CeO 2 ‐supported noble metal clusters are attractive catalytic materials for several applications. However, their atomic dispersion under oxidizing reaction conditions often leads to catalyst deactivation. In this study, the cluster formation threshold is rationally adjusted by using a mixed ‐Al O 3 support. The preferential location of Pd on islands high local surface concentration and promotes in situ small at rather low loading (0.5 wt %), which shown be active species CO...
The hydroformylation of alkenes is a cornerstone transformation for the chemical industry, central both functionalizing and extending carbon backbone an alkene. In this study, silica‐supported crystalline rhodium sulfide nanoparticles are explored as heterogeneous catalysts in reactions, it found that Rh x S y systems ( = 17, 15 or 2, 3 with 1 wt% on SiO 2 ) greatly outperform metallic nanoparticles. These prove to be exceptionally competitive when benchmarked against other cutting‐edge...
