A series of Fe x (PO 4 ) y (OH) z ·nH 2 O microcrystals were prepared by the hydrothermal reaction at 150 °C. The ratio of Fe 2+ /Fe 3+ in Fe x (PO 4 ) y (OH) z ·nH 2 O microcrystals can be adjusted by using Na 2 S 2 O 3 ·5H 2 O as a reducing agent. The morphology control of Fe x (PO 4 ) y (OH) z ·nH 2 O microcrystals was realized through regulating the molar ratio of LiAc·2H 2 O/FeCl 3 . Further, the morphology, structure and composition of Fe x (PO 4 ) y (OH) z ·nH 2 O microcrystals were also investigated by x‐ray diffraction (XRD), x‐ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) techniques.
