Niedertemperatur-Pellistoren mit Au-Pd-imprägniertem mesoporösem Co3O4 als katalytische Schicht

Abstract: ZusammenfassungHerkömmliche Pellistoren auf der Basis von porösen Al2O3 als Trägermaterial für einen Pd-Katalysator benötigen eine Arbeitstemperatur von rund 450 °C für den Nachweis von Methan. Durch diese hohe Temperatur sind sie anfällig für „Vergiftungen“ durch Silizium-haltige Gase. Eine gute Alternative bieten Co3O4-basierte Träger in Kombination mit bimetallischen katalytischen Nanomateria… Show more

“…Moreover, Au-Pd nanoparticles are also observed inside the surface near pores. In combination with previous investigations in transmission, we conclude that the AuPd-nanoparticles are homogenously dispersed throughout the complete mesoporous network [22,23]. Thus, the mesoporous system of Co 3 O 4 provides a high specific surface area for anchoring nanoparticles and a high number of active sites for catalytic reactions, which explains the high activity of the catalyst.…”
