“…Experimentally it is found that the H 2 selectivity can reach more than 90% at 30-40 • C on Ni/SiO 2 catalyst for hydrazine decomposition [26]. Additionally, by doping small amount of Ir or Pt, e.g.…”

“…[78][79][80] Most of the reports on the decomposition of hydrazine show the presence of ammonia as a product, whereas the selective decomposition of hydrazine to exclusive hydrogen is scarce. [77] Zhang and co-workers have explored in detail the gas phase catalytic decomposition of hydrazine diluted in argon (3 % v/v) over a range of SiO 2 -and Al 2 O 3 -supported catalysts of ferrous and platinum group metals. [77] They found that the supported Fe, Ru, Co, and Rh metal catalysts exhibited 100 % selectivity for hydrogen only at high temperatures (> 300 8C).…”

Liquid‐Phase Chemical Hydrogen Storage: Catalytic Hydrogen Generation under Ambient Conditions

There is a demand for a sufficient and sustainable energy supply. Hence, the search for applicable hydrogen storage materials is extremely important owing to the diversified merits of hydrogen energy. Lithium and sodium borohydride, ammonia borane, hydrazine, and formic acid have been extensively investigated as promising hydrogen storage materials based on their relatively high hydrogen content. Significant advances, such as hydrogen generation temperatures and reaction kinetics, have been made in the catalytic hydrolysis of aqueous lithium and sodium borohydride and ammonia borane as well as in the catalytic decomposition of hydrous hydrazine and formic acid. In this Minireview we briefly survey the research progresses in catalytic hydrogen generation from these liquid-phase chemical hydrogen storage materials.

“…For example, on the industrially used iridium catalyst for this process, the main products are NH 3 and N 2 at low temperatures, and the selectivity to H 2 is very low ($2%). 6,7 NAN bond is much easier to cleavage than NAH bond over Ir surface, which leads to the formation of NH 3 in the final products. 8 Thereby, it is a great challenge of developing efficient catalysts for the selective decomposition of hydrous hydrazine to H 2 production.…”

A noble metal-free catalyst, Raney Ni, exhibited > 99% selectivity toward H 2 for hydrous hydrazine decomposition in basic solution at 30 C. The particle size of the initial Ni-Al alloy and the concentration of additional alkali influenced the H 2 selectivity on Raney Ni catalysts. This convenient route provides great potential for industrial application of hydrous hydrazine as a promising hydrogen storage material.
