Mesostructured manganese phosphonate (MnP) with a uniform nanorod morphology has been prepared through an easy surfactant-mediated procedure, in which cetyltrimethylammonium bromide acts as a structure-directing agent and 1-hydroxyethane 1,1-diphosphonic acid is used as the phosphonic bridging molecule. Suitable interaction between the micelles and precursors is proved to play an essential role in the formation of a mesophase. By optimizing the reaction conditions (e.g., Mn/P ratio, pH, and aging time), a mesostructure can be realized in manganese phosphonate. Furthermore, our MnP sample shows great potential as a high-performance pseudocapacitive material due to the abundant accessible active sites and rapid ion/electron transportation arising from the unique mesostructural architecture.

介孔结构膦酸锰的合成及其在储能方面的应用前景

通过简单的表面活性剂介导的方法制备了具有均匀纳米棒形态的介观结构的膦酸锰（MnP），其中十六烷基三甲基溴化铵充当结构导向剂，而1-羟基乙烷1,1-二膦酸用作膦酸桥联分子。胶束与前体之间的适当相互作用被证明在中间相的形成中起着至关重要的作用。通过优化反应条件（例如，Mn / P比，pH和老化时间），可以在膦酸锰中实现介观结构。此外，我们的MnP样品由于其独特的介观结构而具有大量可访问的活性位点和快速的离子/电子传输能力，因此具有作为高性能伪电容材料的巨大潜力。
