Microcalorimetric Study of the Catalytic Properties of SBA-15 Modified with Cu or Fe for Adsorption/oxidation of Methyl mercaptane

Reduction of Typical Diesel NOx Emissions by SCR-NH3 Using Metal-Exchanged Natural Zeolite and SBA-15 Catalysts

“…The incorporation of Cu in the zeolite matrix causes suppression of the low-intensity bands (670 and 726 cm −1 ) and an increase in the intensity of the band at 794 cm −1 . In addition, the shoulder at 913 cm −1 is shifted to the high-frequency region, appearing as a more defined band with greater intensity at 967 cm −1 , indicating the existence of metal ions in CLIN network, M-[SiO 4 ] [45,46]. Likewise, the 1018 cm −1 band is moved 39 cm −1 to a higher frequency region (1057 cm −1 ).…”

Competitive adsorption mechanisms of Cd(ii), Cu(ii) and Pb(ii) on bioinspired mesoporous silica revealed by complementary adsorption/isothermal titration calorimetry studies

“…Isothermal titration calorimetry (ITC) appeared as a good technique to obtain information both on the adsorption thermodynamics and competitive effects in this system. 41 Originally designed for liquid-liquid thermodynamic studies, the recent years have seen an increase in the use of ITC for solid-liquid interactions 35,[41][42][43][44][45][46] but to the best of our knowledge, very few studies have focused on the application of ITC for solid-liquid interactions on grafted mesoporous silica.…”
