The monolayer flake-like zirconia was prepared by a clean molten salt method, which does not require any adsorbent and template. The effects of NaOH on the composition, morphology and structure of zirconia were studied by XRD, IR, Raman, FE-SEM and TEM. The nanostructures synthesized under 2 wt% NaOH exhibit definite flake-like geometry with a large percentage of (0 0 1) plane, which measure approximately 1.8 μm long and 80 nm thick. This concomitant phase and morphology change originate from the martensite transformation of metastable tetragonal zirconia. The as-prepared zirconia sheet has potential utility in fields as diverse as chemical adsorption and photocatalysis.

通过清洁的熔融盐法制备单层薄片状氧化锆，该方法不需要任何吸附剂和模板。用XRD，IR，拉曼，FE-SEM和TEM研究了NaOH对氧化锆的组成，形貌和结构的影响。在2 wt％的NaOH下合成的纳米结构表现出明确的片状几何形状，具有很大比例的（0 0 1）平面，其长约1.8μm，厚80 nm。这种伴随的相态和形态变化源自亚稳四方氧化锆的马氏体转变。所制备的氧化锆片材在化学吸附和光催化等领域具有潜在的实用性。
