Abstract
COx-free hydrogen production; cobalt-based catalysts for ammonia decomposition; cerium–barium promoter in cobalt catalysts.
Highlights
The search for cleaner energy carriers points to hydrogen as the most interesting candidate.[1,2,3] for the “hydrogen economy” to become a reality, the safe and economical storage of this gas is of the utmost importance.[1]
The composition of the catalyst precursors obtained by precipitation and subsequent calcination was analyzed by ICP
The specific surface area and pore volume increased significantly as a result of the addition of cerium in relation to the pure cobalt oxide (Co without Ce) sample. This increase in surface area upon incorporation of Ce suggests that cerium plays a role of structural promoter, which improves the surface of the catalyst precursors and prevents the sintering of these materials during calcination.[32]
Summary
The search for cleaner energy carriers points to hydrogen as the most interesting candidate.[1,2,3] for the “hydrogen economy” to become a reality, the safe and economical storage of this gas is of the utmost importance.[1]. From the hydrogen uptakes evaluated by the H2-TPR measurements (Table 2), it is concluded that Co3O4 is not completely reduced to cobalt metal for these samples under the TPR conditions, with smaller reduction degrees achieved for the samples with higher cerium content.
