Sumario:[Image: see text] Stacking layered metal hydroxide films parallel to a substrate is challenging. Here, we demonstrate a simple and rapid electrodeposition method for stacking magnesium hydroxide layered films. Room-temperature cathodic electrolysis (40 mA cm(–2)) in a Mg(NO(3))(2) aqueous solution induces the deposition of ⟨001⟩-oriented Mg(OH)(x) layered films stacked parallel to the substrate at the deposition rate of ∼2 μm min(–1). The obtained Mg(OH)(x) layered films undergo an overall oriented transformation by heat treatment to form ⟨111⟩-oriented nanoporous MgO films.
