As-prepared magnetically separable photocatalysts differing in γ-Fe2O3 loading (3, 8, 13, 20 and 30 wt.%) were characterized by XRD, TEM, thermal analysis, Mössbauer and magnetic measurements. The photocatalytic efficiency of the nanocomposite catalysts was evaluated using a chloroacetanilide herbicide (propachlor) in water as model compound. The primary degradation of propachlor followed pseudo-first-order kinetics according to the Langmuir–Hinshelwood model. Generally, all magnetic photocatalysts exhibit good catalytic activity towards organic pollutants, do not suffer from photodissolution and can be reused several times without any decrease in their photocatalytic activity.Applied Catalysis B: Environmentalhttp://hdl.handle.net/11400/10677Belessi, V., Lambropoulou, D., Konstantinou, I., Zboril, R., Tucek, J., et al.
