Furthermore, density functional theory (DFT) calcu- lation, served as a powerful tool for studying the catalysis and reaction mechanism21, was used to investigate the adsorption configuration of the substrate molecules with different groups on the catalyst surface and explore the possible reaction ...
plane, the crystal size, surface oxygen vacancies and lattice defects, and provide some guidance for the rational design and synthesis of catalysts with the metal/oxide configuration. Experimental Sections General considerations. All the solvents and reagents were of analytical grade and were used ...
Off-stoichiometric copper chromium oxide delafossite received lately a great interest due to its high p-type electrical conductivity and adequate optical transmittance in the visible range. However, for a suitable integration in active devices such as p-
For practical circumstance, there is generally a small amount of H2O vapor in the feed gas. Thus, the H2O resistance was performed at 58 °C on the best Cu/CeO2-R catalyst (Fig.2a). Interestingly, it could be seen that the introduction of 3% H2O at 58 °C resulted in an obviou...
Copper ferrite, belonging to the wide and technologically relevant class of spinel ferrites, was grown in the form of t-CuFe2O4 nanocrystals within a porous matrix of silica in the form of either an aerogel or a xerogel, and compared to a bulk sample. Ex
The separation of H2, CH4, and CO was achieved with a Molecular Sieve 5A column (10 ft ˆ 1/8 in), whereas CO2, H2O, C2H4, C2H6, C2H5OH, CH3CHO and CH3COCH3 were separated in a Poraplot Q column (10 ft ˆ 1/8 in) in a series bypass configuration. The equations used to ...
The morphology of fresh and spent catalysts was investigated by scanning electron microscopy (SEM) using a JEOL 6300 microscope, coupled with EDX (Oxford Link ISIS-2000) for the determination of local elemental composition. 4.2.4. Redox Characterization (H2-TPR) TPR studies were elaborated in a ...
