In addition, a certain amount of CH3COONa (NaAc) was necessary for the formation of such unique FeWO4 microstructures. The photocatalytic property of as-synthesized hierarchical FeWO4 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 FeWO4 platelike microcrystals show a small ferromagnetic ordering at low temperature because of spin-canting of antiferromagnetic materials and surface spins of FeWO4 nanoparticles. %I ACS Publications
