Kinetic manipulation of the morphology evolution of FePO4 microcrystals: from rugbies to porous microspheres
Abstract
In this paper, we fabricated crystalline FePO4 microstructures with controlled morphologies at relatively low temperature through kinetic manipulation. The morphology evolution was directly observed during the experiments. The morphologies were mainly determined by the amount of the H3PO4 in the reaction system. The morphologies of the obtained FePO4 changed from rugby to porous microsphere through controlling the concentration of the H3PO4. During the growth of the final porous microspheres, we observed some interesting processes which revealed the special configuration of FePO4 micro/
