“…This may be attributed to the Pd 0 loaded on the surface of this MOFs material being shed off during the reaction with the structural damage of NH 2 -MIL-101(Cr) and the reduction of surface area, and then was gathered in aqueous solution. It was similar to our previous research results from MHACF-MIL-101(Cr) [44,45]. As established by the hard/soft acid/base principle, a more stable framework could be formed by high-valent metal cations by stronger coordination bonds.…”

“…•OH could be continuously generated by using only trace amount Ferrous ion in that system though the MIL-101(Cr) will be gradually damaged during the reaction process [44,45]. These two papers would serve as a basis for further studies on the subject matter, with particular concentrates on the reduction of iron sludge in Fenton system, and how improvements can be on suitable catalytic materials.…”

In this paper, a novel improvement in the catalytic Fenton reaction system named MHACF-NH 2 -MIL-101(Cr) was constructed based on H 2 and Pd/NH 2 -MIL-101(Cr). The improved system would result in an accelerated reduction in Fe III , and provide a continuous and fast degradation efficiency of the 10 mg L -1 4-chlorophenol which was the model contaminant by using only trace level Fe II . The activity of Pd/NH 2 -MIL-101(Cr) decreased from 100% to about 35% gradually during the six consecutive reaction cycles of 18 h. That could be attributed to the irreversible structural damage of NH 2 -MIL-101(Cr).

Among the existing metal–organic frameworks (MOFs), MIL‐101(Cr) is renowned for its stability in air and water. As a result, MIL‐101(Cr) has numerous potential applications ranging from adsorptive cooling to catalysis. The industrial‐scale production of MIL‐101(Cr) is necessary before realizing these applications. Yet, there remain two main bottlenecks in preparing MIL‐101(Cr) in bulk: the toxicity of hydrofluoric acid (HF) used in conventional MIL‐101(Cr) synthesis and the challenge of ensuring that the as‐prepared MIL‐101(Cr) is highly porous with specific Brunauer–Emmett–Teller surface area (SBET) above 4000 m2 g−1. On the laboratory scale, MIL‐101(Cr) often presents SBET 2300–3500 m2 g−1. The synthesis and purification procedures often influence the yield, particle size, porosity, and other properties of MIL‐101(Cr). This critical review examines trends in MIL‐101(Cr) preparation procedures and the MOF's resulting properties to elucidate areas for improvement toward its real‐world applications. The purification processes for conventional HF‐based MIL‐101(Cr) whereby porosities vary despite the same synthesis approach are first investigated. Next, the reported additives for substituting HF and their influence on the resulting MIL‐101(Cr)’s porosity and particle size are discussed. The selection of additives may be application‐specific: exemplified in the examination of MIL‐101(Cr)’s preparation, its corresponding water sorption capacity, and desiccant‐related applications.

The construction of accelerated catalytic Fenton reaction based on Pd/MIL-101(Cr) and H₂

Abstract: A novel catalytic Fenton system based on H2 and the solid catalyst Pd/MIL-101(Cr) (MHACF-MIL-101(Cr)) was developed at normal temperature and pressure. In this system, the reduction process of FeIII back to FeII was accelerated significantly.
