alpha-Co(OH)(2) Thin-Layered Cactus-Like Nanostructures Wrapped Ni3S2 Nanowires: A Robust and Potential Catalyst for Electro-oxidation of Hydrazine
Original language description
It is of significant urgency to fabricate highly active catalysts for electro-oxidation of hydrazine for application in direct hydrazine fuel cells (DHFCs). Thus, in this work we grow threedimensional (3-D) α-Co(OH)2 thin-layered cactus-like nanostructures (shell) on the surface of Ni3S2 nanowires (core) enveloped nickel (Ni) foam substrate. HRTEM images clearly reveal that the α-Co(OH)2 thin-layered cactus-like nanostructures (shell) are evenly surrounded on the surface of Ni3S2 nanowires (core). Notably, α-Co(OH)2/Ni3S2 thin-layered cactus-like nanowires modified Ni foam displays an enhanced electro-oxidation of hydrazine (340 mA current response and the onset oxidation potential of -1.10 V) than α-Co(OH)2 sponge-like, and Ni3S2 nanowire structures. The obtained enhanced electro-catalytic response is mainly due to its electron rich Ni active centers, larger electrochemically active surface area, higher electrical conductivity, and porous surface-structure formed by growing α-Co(OH)2 thin-layered cactus-like nanostructures on the Ni3S2 nanowires, henceforth increasing the inherent activity and the number of available active sites/spots. Further, the α-Co(OH)2/ Ni3S2 thin-layered cactus-like nanowire catalyst shows notablestability (stable for more than a week) towards electro-oxidation of hydrazine. Thus, as fabricated cactus-like thin-layered α- Co(OH)2/Ni3S2 core-shell nanowires catalyst can be considered as potential and robust catalyst for electro-oxidation of hydrazine.
