Coating mesoporous alumina onto the macropore walls of monolithic α-Al2O3 and its use as catalyst support for preferential oxidation of CO
Abstract
Monolithic α-Al2O3 with a mesoporous Al2O3 layer coated onto its macropore walls was successfully prepared. Macroporous monolithic polystyrene foams were filled with alumina hydrosol followed by drying and high temperature
