Surface activation of mesoporous ordered silica materials by aluminum and rhodium, their characterization and catalytic activity for N2O decomposition
Original language description
Three different mesoporous ordered silica materials such as MCM-41, MCM-41 with aluminum and SBA-15 were prepared. Samples with aluminum (2 ? 3 wt%) grafted on the surface by molecular designed dispersion method (MDD) and aluminum (2 ? 5 wt%) incorporated into MCM-41 were synthesized. In further step, rhodium (1.3 - 2.9 wt%) was used as an active metal for the catalytic reaction of N2O decomposition. Prepared catalysts were characterized by nitrogen sorption, electron-probe microanalysis, energy dispersive X-ray analysis, temperature programmed reduction of hydrogen, temperature programmed desorption of ammonia and UV-vis-DR spectroscopy. The activity of catalysts was in the order Al(incorporated)-MCM-41+Rh > MCM-41+Al(grafted)+Rh > SBA-15+Rh = MCM-41+Rh. The role of different supports influencing the properties of active sites created by rhodium ions is discussed.
