In addition, a certain amount of CH<sub>3</sub>COONa (NaAc) was necessary for the formation of such unique FeWO<sub>4</sub> microstructures. The photocatalytic property of as-synthesized hierarchical FeWO<sub>4</sub> microcrystals has been first studied, which shows excellent photocatalytic activity for the degradation of rhodamine B (RhB) under UV and visible light irradiation (modeling sunlight). Moreover, magnetic measurement indicates that hexangular FeWO<sub>4</sub> platelike microcrystals show a small ferromagnetic ordering at low temperature because of spin-canting of antiferromagnetic materials and surface spins of FeWO<sub>4</sub> nanoparticles.
