Abstract Considering the novel applications of metal organic frameworks (MOFs) in photocatalytic fields, in this study, new nanostructures of Eu-MOF have been synthesized using effective, facile, cost-effective, and fast reverse micelle (RM) as well as ultrasound assisted reverse micelle (UARM) methods under the optimal conditions. In order to improve the properties, these nanostructures were extended in the form of fibrous networks. To find nanostructure with distinctive features, thermogravimetric analysis, Fourier transform infrared spectroscopy, field emission scanning electron microscopy, X-ray diffraction, and N2 adsorption/ desorption analysis were applied. The results revealed that the samples synthesized by UARM method had a crystallite size of 27.5 nm and thermal stability of 252 °C. Therefore, the UARM Eu-MOF sample was selected as the desirable sample. Also, its application was studied as a novel nanophotocatalyst with the ideal properties in the field of brilliant green dye removal. The photocatalytic results indicated the influence of initial dye concentration, pH, photocatalyst dosage, and contact time parameters on the photocatalytic properties with an efficiency of 99.80%. This study provides a new strategy for developing desirable methods, extended structures, and the photocatalytic applications of these products. Keywords UARM method . Eu-MOF nanostructure .

Introduction Unique physical and chemical properties such as large specific surface area, structural diversity, tunable pore channels, flexible functionalities, and high thermal stability have made metal-organic frameworks (MOFs) one of the novel porous crystalline materials (Zhou et al. 2012; Akbarzadeh et al. 2020). These hybrid materials have been widely employed in various applications including gas storage (Li et al. 2018; Llewellyn et al. 2008), catalysis (Puthiaraj et al. 2014; Huang et al. 2017), molecular separation (Lee et al. 2012), Responsible Editor: Sami Rtimi * Tayebeh Shamspur [email protected] 1
