FULL PAPER Active Sites in Olefin Metathesis over Supported Molybdena Catalysts
Metathesis of propene to ethene and 2-butenes was studied over a series of MoOx/SBA-15 catalysts (molybdenum oxide supported on mesoporous silica SBA-15; Mo loading 2.1~13.3 wt%, apparent Mo surface density 0.2~2.5 nm). The catalysts have been prepared by an ion exchange technique. Nitrogen adsorption, HMAS-NMR, Raman, and FTIR spectroscopies were applied to characterize the catalysts. Adsorpti...
متن کاملOxidation of SO2 over Supported Metal Oxide Catalysts
A systematic catalytic investigation of the sulfur dioxide oxidation reactivity of several binary (MxOy/TiO2) and ternary (V2O5/ MxOy/TiO2) supported metal oxide catalysts was conducted. Raman spectroscopy characterization of the supported metal oxide catalysts revealed that the metal oxide components were essentially 100% dispersed as surface metal oxide species. Isolated fourfold coordinated ...
متن کاملVapour phase hydrogenation of nitrobenzene over metal ( Ru , Ni , Pt , Pd ) supported on Ca 5 ( PO 4 ) 3 ( OH ) catalysts
Vapour phase hydrogenation of nitrobenzene is carried out over metal (Pt, Pd, Ru, Ni) supported on hydroxyapatite (HAP) catalysts at atmospheric pressure and low temperatures ranging from 225–350 °C. The time-on-stream analysis reveals that 2 wt.%Pd/HAP is quite stable up to 6 h of continuous operation and is found to be an efficient catalyst. The other metal catalysts suffer deactivation, whic...
متن کاملCO oxidation on TiO2 supported gold catalysts
The aim within this project was to optimise the CO oxidation over TiO2 supported gold catalysts, focusing on two different preparation methods; deposition precipitation (DP) and photodeposition (PD), using different types of TiO2 and varying the theoretical gold loading. The catalyst were characterised with TEM (size) and ICP-AES (loading). For DP catalysts, the support is important for high ac...
