Single Crystalline Ultrathin Nickel–Cobalt Alloy Nanosheets Array for Direct Hydrazine Fuel Cells

Ultrathin 2D metal alloy nanomaterials have great potential applications but their controlled syntheses are limited to few noble metal based systems. Herein NixCo1−x alloy nanosheets with ultrathin (sub‐3 nm) single‐crystalline 2D structure are synthesized through a topochemical reduction method. Mo...

Zusammenfassung:	Ultrathin 2D metal alloy nanomaterials have great potential applications but their controlled syntheses are limited to few noble metal based systems. Herein NixCo1−x alloy nanosheets with ultrathin (sub‐3 nm) single‐crystalline 2D structure are synthesized through a topochemical reduction method. Moreover, the optimized composition Ni0.6Co0.4 alloy nanosheets array exhibits excellent performances for hydrazine oxidation reaction and direct hydrazine fuel cells.
