In this work, a Cu foil supported array of leaf-like Co3Ni microstructures composed of well aligned nanorods was synthesized by a facile electroless process. It was found that the as-prepared Co3Ni array exhibited ferromagnetic properties with enhanced coercivity. The static contact angle of water on the surface of the Co3Ni array could reach 154.7 degrees, indicating that the Co3Ni array displayed superhydrophobic properties. In addition, the as-prepared Co3Ni array showed high catalytic activity in the hydrolysis of ammonia borane for hydrogen generation. More importantly, the Co3Ni array catalyst still retained ca. 91% of its original catalytic activity after 6 cycles, exhibiting significantly improved recyclability and reusability in contrast to many nanocatalysts reported in the literature. The high catalytic performance, together with its ferromagnetic and superhydrophobic properties, makes the Co3Ni array a multifunctional material with wide applications in different areas.
