Electrochemical oxidation of hydrazine and its derivatives on the surface of metal electrodes in alkaline media

Preparation of reduced graphene oxide-NiFe 2 O 4 nanocomposites for the electrocatalytic oxidation of hydrazine

“…Hydrazine and its derivatives are broadly utilized in applications including fuel cells, catalysts, blowing agents, corrosion inhibitors, antioxidants, pharmaceutical intermediates, pesticides, plant-growth regulators, and dyes in addition to their use as starting materials in the synthesis of some insecticides and photography materials [1][2][3]. Moreover, hydrazine is a high energy molecule which can be used as a fuel in explosives and rocket propulsion systems [4]. It is also used in hydrazine/air direct-liquid fuel cells are used due to their advanced equilibrium potential, nonexplosive and less toxic in dilute solution [5].…”

“…Controlling the size and morphology of mixed metal oxide nanoparticles (NPs) will improve the performance of the catalyst [19]. The strong van der Waals' M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 4 force of attraction and the high surface energy of metal oxide NPs cause the NPs to aggregate in the absence of capping agents. Therefore, it is necessary to use a capping ligand or solid supports to minimize aggregation as well as improve the morphology and performance of the catalyst [20].…”

Porphyrin Nanorods Modified Glassy Carbon Electrode for the Electrocatalysis of Dioxygen, Methanol and Hydrazine

“…A lot of work has been done to modify various metal electrode surfaces for the dissociation of the NÀH bonds, OÀO bonds and the C-H bonds. Such metal electrodes include Pt, Au, Ni, Cu, Zn [10][11][12][13][14][15][16][17] and macrocyclic compounds electrode modifiers such as phthalocyanines [18,19] and porphyrins [20][21][22][23][24][25][26]. Other compounds such as Prussian blue [27], alizarin [28], g-MnOOH [16], and polyaniline [29] have been used for the electrooxidation of hydrazine and methanol and the electroreduction of molecular oxygen respectively.…”

Ni-La Electrocatalysts for Direct Hydrazine Alkaline Anion-Exchange Membrane Fuel Cells

“…7,8 Further, Ni-based electrocatalysts have been reported to outperform Pt-based electrocatalysts in high pH environments. [4][5][6][7]14,15 Improved catalytic performances have been obtained from multifunctional catalysts composed of alloyed Ni materials.…”
