Synthesis of porous MnO2 hierarchical structures through controlled precursor adsorption

Abstract

Complex MnO₂ nanostructures were prepared through controlled precursor adsorption. The preferential adsorption of a precursor ion leads to the anisotropic growth of crystals, and even produces crystals of different crystal structures. The thus produced primary anisotropic crystals assemble into porous spherical hierarchical 3D architectures.
