摘要：

本文利用在反应过程中同时添加均相沉淀剂六次甲基四胺和形貌导向剂十六烷基三甲基溴化铵，结合水热反应的方法一步合成了镍钴氢氧化物. 随着六次甲基四胺的水解，层状镍钴氢氧化物可以被合成而且避免了额外碱源的使用；同时，由于反应过程中十六烷基三甲基溴化铵参与的孔径调节，合成出来的镍钴氢氧化物具有可控的介孔尺寸13.4 nm以及较大的比表面积93.6 m² •g^-1. X射线衍射图谱表明合成出来的镍钴氢氧化物构型是α-Ni(OH)₂-β-Co(OH)₂. 扫描电镜表明合成出来的镍钴氢氧化物具有层状的结构. 正是因为层状介孔结构的存在，合成出来的镍钴氢氧化物在1 A•g^-1电流密度下，比电容可以高达1902 F•g^-1；即使电流密度提高到8 A•g^-1，镍钴氢氧化物的比电容仍然可以保持在1250 F•g^-1.

Abstract:

Nickel/cobalt double hydroxide (Ni/Co-DH) has been prepared by facile hydrothermal one-step synthesis method using hexamethylene tetramine (HMT) as a homogeneous precipitating agent and cetyltrimethylammonium bromide (CTAB) as a shape-directing agent. With the hydrolysis of HMT and the use of CTAB, the Ni/Co-DH could be synthesized without additional alkali source, and in the meantime, the Ni/Co-DH exhibited a controlled mesopore size of 13.4 nm and a large BET surface area of 93.6 m² •g^-1 . The X-ray diffraction (XRD) pattern displays that the Ni/Co-DH existed as a mixture of α-Ni(OH)₂-β-Co(OH)₂. The scanning electron microscope (SEM) image shows that the as-prepared Ni/Co-DH took on a layered structure, which leads to a maximum specific capacitance of 1902 F•g^-1 at a current density of 1 A•g^-1. The specific capacitance remained 1250 F•g^-1 when the current density increased to 8 A•g^-1.
