Octahedral jarosite was successfully prepared without extra template using a novel hydrothermal route based on the redox reaction between KMnO 4 and (NH4) 2 Fe(SO 4 ) 2 ·6H 2 O. The mass ratio of (NH 4 ) 2 Fe(SO 4 ) 2 ·6H 2 O/KMnO 4 , reaction time, and reaction temperature play key roles in forming octahedral crystals. The chemical composition and microstructure of as‐prepared octahedral jarosite were characterised by X‐ray diffraction, scanning electron microscopy, energy dispersive spectrum, high‐resolution transmission electron microscopy, and selective area electron diffraction. The formation mechanism of octahedral jarosite was discussed preliminarily.
