Ultrathin 2D metal alloy nanomaterials have great potential applications but their controlled syntheses are limited to few noble metal based systems. Herein Ni x Co 1− x alloy nanosheets with ultrathin (sub‐3 nm) single‐crystalline 2D structure are synthesized through a topochemical reduction method. Moreover, the optimized composition Ni 0.6 Co 0.4 alloy nanosheets array exhibits excellent performances for hydrazine oxidation reaction and direct hydrazine fuel cells.
