Abstract

A novel, rapid and simple method is described for the synthesis of magnetic MIL-100(Fe) with novel Fe3O4 morphology, which significantly improved the sustainability of conventional fabrication processes in several aspects. The magnetic MOFs were prepared (i) in one pot (instead of multiple steps), (ii) at room temperature (instead of temperatures over 150 °C), (iii) within a few hours with excellent yield (instead of in few days with low productivity) and (iv) in the absence of any corrosive inorganic acid and organic reagent. The materials were tested in the industrially demanded photocatalytic and photo-Fenton degradation of sodium sulfadiazine. The degradation results indicated that the Fe3O4 nanorods could accelerate the catalytic efficiency. The catalyst would be of potential application due to its stable catalytic activity in repeated reaction cycles and no need for regeneration. Therefore, the MIL-100(Fe) and magnetic MIL-100(Fe) proposed in this study are ideal catalysts for the heterogeneous degradation of sodium sulfadiazine.
