在这项工作中，我们利用真菌--自然界中最常见的生命形式之一--生产了具有高电化学电容行为的氧化镍纳米结构。枝孢子菌具有管状结构，是一种极具吸引力的生物模板。采用化学沉淀法在真菌表面制备了纳米多孔微管。用透射电子显微镜研究了生物合成的NiO微管的形态特征。比表面积为119.72 m(2)g(-1)，平均孔径分布为7.5nm.在0.8Ag(-1)下观察到最大电容值为334Fg(-1)，1000次循环后的电容保持率约为95%。
In this work, we produced nickel oxide nanostructures that show high electrochemical capacitive behaviour, using fungus - one of the most common life forms in nature. Cladosporium cladosporioides fungi are particularly attractive biotemplates due to their tubular structures. The nanostructured porous microtubes were prepared by chemical precipitation onto fungi. The morphological properties of the biosynthesized NiO microtubes were studied by transmission electron microscope (TEM). The Brunauer-Emmett-Teller (BET) surface area was found to be 119.72 m(2) g(-1) with an average pore size distribution of 7.5 nm. A maximum capacitance value of 334 F g(-1) was observed at 0.8 A g(-1), and a capacitance retention of approximately 95% was obtained after 1000 cycles.
