“…MIL-88A with synthesis temperature of 85°C and crystallization time of 2h obtained the optimal performance for catalytic degradation of OG as shown in Fig.2A and Fig.2B. The residual OG first decreases and then increases with the increasing of synthesis temperature of MIL-88A, and this could be caused by the difference of S BET , dissolved quantity of Fe and pore volume which was proved by Wang et al [28]. Besides, with the increase of synthesis temperature, the size of samples became larger and the surface of samples were cracked [28].…”

“…Therefore, MIL-88A was not suitable produced at high temperature because of the damage the crystal structure. Similarly, numbers of MIL-88A were in growth stage when the crystallization time was short and most of the MIL-88A were already in full-grown stage on the whole field of vision when the crystallization time was longer as shown in SEM reported by Wang et al [28]. Whether the aging time too long or too short was not conducive to the formation of catalytic materials.…”

“…With the increase of raw materials added in a same container, the quality of synthesized catalyst and particle size should become more and bigger, and this would lead to a decrease in the activity of the catalyst. The excessive presence of fumaric acid also inhibited the reaction [28], so catalyst with high dosage of fumaric acid such as MIL-88A&Rp-4 and Rp-5 showed a weaker catalytic performance than others. In summary, MIL-88A with n (Fumaric acid/ Fecl 3 .6H 2 O) =1:1 was the best choice.…”

Abstract. In this paper, the effect of preparation conditions of the catalyst MIL-88A were investigated. The results shows that MIL-88A with the raw materials proportion of n (Fumaric acid/ Fecl 3 ·6H 2 O)=1:1, the synthesis temperature of 85°C and crystallization time of 2h, activation temperature of 100°C and drying time of 6h, which would be achieved the optimal catalytic performance on degradation of orange G (OG) through PS activation. Furthermore, it was the first attempt to apply MIL-88A in removing dibutyl phthalate (DBP) and obtained the ideal result. The removal rate of DBP can reach up to 76.4% catalyze by MIL-88A&St-3/Ct-2. It was indicated that MIL-88A with suitable preparation conditions would be a high efficiency catalyst in the application of advanced oxidation processes for degrading contaminants.

Metal-organic frameworks (MOFs) are best known for their great structural diversity. The uniformity in the properties of MOFs is mainly governed by the size and morphology of the particles. In the present research, iron-MIL-88A was prepared by a modulator-assisted solvothermal method, and the role of modulating agents in the formation process of MOF particles was investigated. Acetic acid and formic acid were chosen as monoligand modulating agents. The changes in morphology and size distribution of the products were scrutinized by using SEM micrographs. Both modulators clearly interfered with the crystallization process through their attachment to the reactive sites. At low modulator content, the primary diamondlike char- [a]

The synthesis of hierarchical or nanosized metal‐organic framework (MOF) superstructures is highly desirable. However, the development of synthetic methods for designed MOF structures via mechanochemical reaction remains extremely limited. We discovered the eco‐friendly and fast strategy that mechanochemical reaction of FeCl3·6H2O and sodium fumarate resulted in Fe‐MIL‐88A MOF hierarchical superstructures. The resulting MOFs possesses a higher surface area than conventional MIL‐88A. The key finding is that the types of the medium during mechanochemical reaction influence on the morphology of MIL‐88A MOFs, generating 3D superstructure and 1D nanorod. We believe that the synthetic strategy adopted opens the door for the modulation of MOF morphologies under mechanochemical condition.
