·2H2O. Hirshfeld surface analysis was employed to determine the most important intermolecular interactions in the crystallographic structures. The structures of both complexes were further examined using density functional theory and natural bond orbital analysis. The photocatalytic decomposition of methylene ...
The factors that affect the sintering and aggregation of copper particles are also different. In general, the larger the specific surface area of the catalyst, the less likely the copper nanoparticles are to aggregate [68]. When the active metal–support interaction is weak, the catalyst is ...
[24] supplementary information; Figure S5: Optical absorption spectra measured in reflexion with integrating sphere of Noheda red and orange samples; Figure S6: Ternary diagram for SiO2-Cu2O-PbO systems in equilibrium with metallic copper [45]; Figure S7: Pairs of elements for all red and ...
surface area than that obtained with the pure TiO2material, and the pore volume increased from 0.26 to 0.48 cm3/g, which can be attributed to structural defects in the titania due to the presence of Cu cations [34]. The average pore diameter remained constant at 5.7 nm in both catalysts....
In another study regarding layered titanate-intercalated pyridine, two values of the d-spacing were reported: (i) a value of 3 Å when pyridine was inserted flat into the interlayer space and (ii) 5.8 Å when pyridine was intercalated perpendicular to the surface [30]. The chain length ...
surface area and volume was achieved when CTAB was embedded within ordered mesoporous silica nanoparticles. Physicochemical characterization was performed by using structural and spectroscopic techniques to elucidate the properties of hierarchical SAPO-34 before and after Cu introduction. The speciation of ...
The leaching effect was studied against CO2 reactivity and was shown to significantly increase the materials’ surface area, enrich the porosity, alter the nitrogen nature, and deplete the Cu nanoparticles. The effect of those parameters was reflected in the materials’ electrochemical performances. ...
The specific surface area, water absorption, microstructure, phase analysis, functional group analysis, and adsorption capability of copper ions by metakaolin based alkali activated materials as adsorbents were evaluated. The water absorption test on the samples revealed that the sodium silicate to sodium...
