Surface activation of mesoporous ordered silica materials by aluminum and cobalt, their characterization and catalytic activity for N2O decomposition
Original language description
Three different mesoporous ordered silica materials such as MCM-41, MCM-41 with grafted and incorporated aluminum and SBA-15 were prepared by the molecular designed dispersion method (MDD). In further step, cobalt (1-16 wt%) was used as an active transition metal for the catalytic reaction of N2O decomposition. The possible interaction of acetylacetonate complexes as precursors with support surfaces by hydrogen bonding versus ligand exchange mechanism were tested by infrared spectroscopy and thermogravimetric analysis. Prepared catalysts were characterized by nitrogen sorption, electron-probe microanalysis, energy dispersive X-ray analysis, X-ray diffraction, scanning electron microscopy, UV-vis-DR spectroscopy, temperature programmed reduction of hydrogen and temperature programmed desorption of ammonia. The N2O conversion slightly increased with the higher content of aluminum. The role of different supports influencing the properties of active sites created by cobalt ions is discusse
