Description:
The formation of ammonium cobalt (II) phosphate was utilized to synthesize unprecedented 3D structures of Co3O4, triangular prisms and trunk-like structures, via a self-supported and organics-free method. The length of a triangular side of the prepared 3D triangular prisms is ~1.5 mm, and the edge is about ~2 mm. The structure is shaped by stacking hundreds of small nano platelets; diameters and thicknesses of platelets are ~100 nm and ~20 nm, respectively. However, they are not closely packed and the ensuing gaps formed between each platelet are helpful for photocatalytic oxidations as exemplified by the oxidation of isopropanol under visible light irradiation.
