In?situ Investigations of Co@Al ₂ O ₃ Ammonia Decomposition Catalysts: The Interaction between Support and Catalyst

Cracking of ammonia, a hydrogen carrier with high storage capacity, gains increasing attention for fuel cell systems heavy load transportation. In this work, we studied the influence metal loading and synthesis temperatures on properties [email protected]2O3 catalysts. The combination in situ bulk characterization methods surface spectroscopy provides insights into structure-property relation Co catalyst ?-Al2O3 support. At too temperatures, formation CoAl2O4 during or catalytic reaction itself results inactive mixed aluminium spinels which do not contribute to reaction. amount ‘active’ thus varies significantly as well its activity. latter is correlated size reduced particles alumina experiments also highlight that state changes after strongly emphasizes necessity studies.
