Flash synthesis of macroanoporous ZnCo_2O_4 via self-sustained decomposition of metal-organic complexes

摘要

This letter describes the synthesis as well as characterization of the 3D macro-anoporous ZnCo_2O_4 using flash synthesis via self-sustained decomposition of metal-organic complexes. The sample was characterized by X-ray diffraction, SEM/TEM imaging, Raman spectrum and X-ray photoelectron spectroscopy. ZnCo_2O_4 with the 3D hierarchical porous structure consisted of nanopartides has a coral-like shape with a size of tens of micrometers and exhibits the hierarchically porous morphology, in which the walls of the macropores contain smaller nanopores. The results show that the flash synthesis directly decomposing a metal-organic complex is a rapid and feasible route to fabricate macro-/ nanoporous ZnCo_2O_4 with high porosity.
