What is Parallel Aluminum‐Cobalt Oxide Nanosheet Arrays with High‐Temperature Ferromagnetism about?

Parallel nanomaterials can enhance macroscopic properties through strong plasmonic, electronic, or excitonic coupling. They also provide direct and fast ion, electron, or molecular transport paths making them be widely used for sensing, catalysis, and energy storage. Currently, 1D parallel nanomaterials (such as nanowires, nanotubes, and nanorods) are most studied and applied, for example zinc oxide and gallium nitride nanowire arrays for piezoelectric nanogenerators and carbon nanotube arrays for field emission. Parallel nanomaterials possess unique properties and show potential applications in industry. Whereas, vertically aligned 2D nanomaterials have plane orientations that are generally chaotic. Simultaneous control of their growth direction and spatial orientation for parallel nanosheets remains a big challenge. Here, a facile preparation of vertically aligned parallel nanosheet arrays of aluminum-cobalt oxide is reported via a collaborative dealloying and hydrothermal method. The parallel growth of nanosheets is attributed to the latticematching among the nanosheets, the buffer layer, and the substrate, which is verified by a careful transmission electron microscopy study.
