Mesoporous slit-structured NiO for high-performance pseudocapacitors†
Abstract
Mesoporous slit-structured NiO materials were prepared through a simple hydrothermal route with sodium dodecyl benzene sulfonate (SDBS) as an additive. The as-prepared NiO samples presented high specific capacitance of over 1700 F g−1 in the potential range from 0.10 to 0.56 V (vs. Hg/HgO/6 mol L−1
