Glass-Ceramics Foam for Hydrogen Production

open access: yesChemical Engineering Transactions, 2015
Glass-ceramic foams belonging to the LZSA (Li2O-ZrO2-SiO2-Al2O3) system were processed as catalytic supports for the ethanol decomposition. The active phases of the support (Ni, Co) were prepared by wet impregnation. The impregnated supports were dried, calcined and reduced under a H2 flow at 700 °C for 120 min.
