The effect of acid treatment in mixed MnOx–CeO2 samples has been investigated the catalytic total oxidation formaldehyde. no on textural and redox properties materials when Mn is stabilized a solid solution (Mn content below 50%). However, these were found to be highly altered by solubility limit ceria was exceeded above This enabled access primary porosity oxidized manganese species higher state via dismutation reaction. As result, activity pure oxide, after chemical activation,...
HAP solids were prepared with different Ca/P ratios and Na<sup>+</sup>cations before being characterized by XRD, XPS, LEIS, NMR, IR, TGA. Their acid–base properties then measured discussed in relation to the characterization results.
Copper catalysts prepared by chemisorption-hydrolysis technique over silica (Cu/Si) and silica-alumina (Cu/SiAl) supports were studied to understand the role of support on nature surface properties copper species stabilized their surfaces. The morphological phases have been characterized complementary techniques, such as HRTEM, EXAFS-XANES, EPR, XPS, FTIR. For FTIR investigation, molecular probes (CO NO) also adsorbed surfaces test reactivity species. Moreover, catalytic performances two...
The acidity of a prereduced Cu/SiO2 catalyst was extensively investigated by means FT-IR adsorbed pyridine and titration with 2-phenylethylamine in cyclohexane. Comparison the parent CuO/SiO2 material, which already shown to exhibit Lewis acid sites due high dispersion CuO phase, provided evidence that reduction this phase metallic state increases material. This allowed us set up bifunctional showing acidic hydrogenation activity, both ascribable presence metal particle, without need an...

The were characterized in their bulk (XRD, redox cycles H2 and O2) surface (N2 adsorption, SEM, XPS, DRS) properties. Copper species found be uniformly spread the as small aggregates both low high loaded samples. Spectroscopic evidence agrees Cu2+ presence an axially distorted octahedral environment...
Niobium oxide catalytic phase was dispersed in/over silica host structures by using different Nb sources (ammonium niobium oxalate complex and pentaethoxide) methodologies (coprecipitation, sol−gel, impregnation). Three series of completely amorphous silica−niobia catalysts were obtained with 5, 15, 30, 45, 60 mass % Nb2O5 coprecipitation (aqueous route, from ammonium oxalate) sol−gel (organic 10, 20 impregnation on a finite silica, oxalate.

This study deals with the use of calcium hydroxyapatite (HAP) materials as adsorbents for removing heavy metal ions from polluted waters.
Among all CO2 reduction reaction (CO2RR) active metals, copper is the only one that exhibits optimal *CO binding energy for multiple electron transfers. Despite such a unique feature, use of Cu-based CO2RR catalysts at industrial scale hampered by large overpotentials and poor selectivity. In this realm, introduction acidic/basic functionalities catalyst surface may help to both overcome scaling relations (i.e., lower overpotential) tune selectivity catalysts. Herein, we demonstrate an...
