Preparation of 3D hierarchical porous Co₃O₄ nanostructures with enhanced performance in lithium-ion batteries.

ABSTRACT: Three-dimensional hierarchical Co₃O₄ microspheres assembled by well-aligned 1D porous nanorods have been synthesized by hydrothermal methods with the help of CTAB and subsequent heat treatment. The morphology and compositional characteristics of the hierarchical Co₃O₄ microspheres have been investigated using different techniques. Based on the SEM and TEM analyses, the growth direction of the nanorods is in the [110] direction. The hierarchical Co₃O₄ microspheres have a comparatively large Brunauer-Emmett-Teller surface area of about 50.2 m²g^-1, and pore size distribution is mainly concentrated at 12 nm. On the basis of the time tracking experiment, a possible growth mechanism has been proposed. It demo
