Prussian Blue Analogue (PBA) Mn(3)Co(CN)(6)·nH(2)O porous nanocubes were successfully synthesized in high yield at room temperature in the presence of poly(vinylpyrrolidone) (PVP) and characterized by X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and transmission electron microscopy (TEM). The effects of synthetic parameters such as surfactant, the ratio of different solvents on the morphology and size of the particles were investigated. The experimental results showed that poly(vinylpyrrolidone) (PVP) and solvent ethanol play critical roles in the formation of uniform porous nanocubes. N(2) adsorption properties indicated that the Mn(3)Co(CN)(6) porous nanocubes with an average diameter of 240 nm possessed a high surface area of 675 m(2) g(-1) with total volume of 0.354 cm(3) g(-1). Moreover, the porous nanocubes showed high CO(2) adsorption at room temperature and 1 bar of pressure. To our knowledge, this is the first report on the synthesis of Mn(3)Co(CN)(6) nanomaterials and their CO(2) adsorption applications at the nanoscale.
普鲁士蓝类似物（PBA）Mn(3)Co(CN)(6)·nH(2)O 多孔纳米立方体制备在室温下，以聚乙烯吡咯烷酮（PVP）为模板，通过水热法合成。通过 X 射线粉末衍射（XRD）、场发射扫描电子显微镜（FE-SEM）和透射电子显微镜（TEM）对其进行了表征。研究了不同的合成参数，如表面活性剂、不同溶剂的比例对颗粒形貌和尺寸的影响。实验结果表明，聚乙烯吡咯烷酮（PVP）和溶剂乙醇在形成均匀多孔纳米立方体形貌中起着至关重要的作用。N(2)吸附性能表明，平均直径为 240nm 的 Mn(3)Co(CN)(6)多孔纳米立方体形貌具有 675 m(2) g(-1)的高比表面积和 0.354cm(3) g(-1)的总孔容。此外，多孔纳米立方体形貌在室温下和 1 巴的压力下对 CO(2)表现出高吸附性。据我们所知，这是首次报道 Mn(3)Co(CN)(6)纳米材料的合成及其在纳米尺度上对 CO(2)的吸附应用。
