ure the magnetization strength which is useful to separate the photocatalyst by simply using a magnet. The temperature dependent magnetization measurement suggests the anti-ferromagnetic (AFM) behaviour of the studied materials with the decrease of Néel temperature (TN) with Mn concentration. The XPS study reveals the presence of multiple oxidation states of Fe(2+/3+) and Mn(4+/3+) in these materials which facilitates the conductivity as well as the oxidation/reduction efficiency at the surface of the catalyst. The band gap reduction
