A promising bimetallic 17 wt % Ni3Fe catalyst supported on γ-Al2O3 was prepared via homogeneous deposition–precipitation for the application in methanation of CO2 to gather more detailed insight into structure and performance compared state-of-the-art systems. X-ray diffraction (XRD) analysis, investigations using scanning transmission electron microscopy (STEM) combined with energy dispersive spectroscopy analysis (EDX) single particles as well larger areas, high-resolution (HRTEM) imaging,...
The selective oxidation of propylene to acrolein is an important reaction in the chemical industry which has been extensively studied over last few decades. Today, spectroscopic, computational, and synthetic approaches allow a renewed view this established well-understood catalytic process at fundamental level. Consequently, revised mechanistic pathway for bismuth molybdates suggested recently. Furthermore, studies concerning local interaction specific surface entities as well concepts from...
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...
Multicomponent Bi-Mo-Fe-Co oxide catalysts prepared via flame spray pyrolysis were tested for selective propylene oxidation, showing high conversion (>70%) and selectivity (>85%) acrolein acrylic acid at temperatures of 330 °C. During extended time-on-stream tests (5–7 days), the retained activity while undergoing diverse structural changes. This was evident on: (a) atomic scale, using powder X-ray diffraction, Raman spectroscopy, absorption photoelectron transmission electron...
Abstract Industrially‐applied mixed metal oxide catalysts often possess an ensemble of structural components with complementary functions. Characterisation these hierarchical systems is challenging, particularly moving from binary to quaternary systems. Here a Bi−Mo−Co−Fe catalyst showing significantly greater activity than Bi−Mo oxides for selective propylene oxidation acrolein was studied chemical imaging techniques the microscale nanoscale. Conventional like XRD and Raman spectroscopy...
Abstract To investigate whether combining L1-regularized iterative sensitivity encoding (SENSE) reconstruction and single-shot echo planar imaging (EPI) is useful in hepatic DWI. Single-shot EPI-DWI with SENSE (L1-DWI) conventional parallel imaging-based (conv-DWI) liver MRI were compared volunteers patients. For the patient cohort, 75 subjects (60 ± 13 years) 349 focal lesions (FLL) included. Patient groups A B used to reduce acquisition time or improve spatial resolution, respectively....
