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) in a Mg(NO) aqueous solution induces the deposition of ⟨001⟩-oriented Mg(OH) layered films stacked parallel to the substrate at the deposition rate of ∼2 μm min. The obtained Mg(OH) layered films undergo an overall oriented transformation by heat treatment to form ⟨111⟩-oriented nanoporous MgO films.
将层状金属氢氧化物薄膜平行于基底堆叠具有挑战性。在此,我们展示了一种用于堆叠氢氧化镁层状薄膜的简单快速的电沉积方法。在硝酸镁水溶液中进行室温阴极电解(40 mA/cm²)会诱导出与基底平行堆叠的〈001〉取向的氢氧化镁层状薄膜的沉积,沉积速率约为2 μm/min。所获得的氢氧化镁层状薄膜通过热处理经历整体取向转变,形成〈111〉取向的纳米多孔氧化镁薄膜。
