Preparation and Characterization of NiO Nanoarrays with Different Hierarchical Porous Structure

摘要

NiO nanoarrays with different hierarchical porous structures were synthesized by using hard-template SBA-15. The analytic results showed that the mesoporous structure parameters of the as-prepared NiO nanoarrays increased obviously with the increase of the addition of SBA-15 to a certain extent. The results may be helpful for the utilization of NiO as supercapacitors.
