• BiOF micro/nanostructures with tunable morphologies were prepared. • NTA molecules was used as structure directing reagents. • The amount of NTA and pH value play vital roles in the reaction. • The photocatalytic activities of BiOF were studied by MG solution under UV light. BiOF with tunable morphologies (polygonal disk-shaped columns, polygonal flakes and square flakes) have been prepared via a facile hydrothermal route, in which nitrilotriacetic acid (NTA) was used as a structure directing reagent. It was found that the morphologies and crystalline structures of the as-obtained BiOF were dependent on the NTA dosage and the pH value. Based on the observation of the photocatalytic selectivity of typical polygonal disk-shaped columns of BiOF towards different types of organic dyes, we further investigated the photocatalytic activities of the BiOF with different morphologies by the degradation of malachite green (MG) solution under UV light irradiation. The results showed that disk-shaped columns of BiOF had the best photocatalytic activity, and the degradation rate of MG reached 95.34 % after 20 min of irradiation. The photocatalytic efficiency was much higher than those of other morphological BiOF micro/nanostructures. The results of this study strongly indicate that BiOF has a broad application prospect in the field of photocatalysis. [ABSTRACT FROM AUTHOR]
