Bicontinuous nanoporous Ni-Fe alloy as a highly active catalyst for hydrazine electrooxidation

Hydrazine Oxidation Electrocatalysis

“…The nitrides, , sulfides, , phosphides, ,,,,− and selenides ,, of Ni and Co are popular HzOR electrocatalysts. E onset values as low as −0.18 to 0 V vs RHE at pH = 14 were reported for such inorganic phases, ,,,− including on carbon ,,,,− or metallic foam supports. ,,,− ,,,− Nanoparticles of FeP, Cu 3 P, Cu 2 Se, and RuP 2 are active toward the HzOR, with reported onsets as low as −0.1 V vs RHE for the Ru-based material. However, most transition metals (including Ni, Co, Cu, and Fe) are most stable as hydroxides at pH 14 at 25 °C. , Thus, the inorganic compounds serve only as precursors, so that the catalytic hydroxide surface forms in situ .…”

An amorphous/nanocrystalline NixP/Ni heterojunction for electrooxidation of hydrazine

“…[8][9][10] In the past few decades, signicant progress has been achieved in developing earth-abundant anode electrocatalysts for the hydrazine oxidation reaction (HzOR). A number of 3d transition metals, [11][12][13][14] alloys [15][16][17][18][19] and compounds (phosphides, [20][21][22][23][24][25][26][27] nitrides, [28][29][30][31] suldes, 32,33 etc.) have been identied as catalytically active materials for the HzOR.…”
