“…In general, MOFs are utilized as Lewis acid catalysts due to their acidic metal center (Dhakshinamoorthy and Garcia, 2012;Mitchell, 2013), high surface area and tunable porosity. But the weak stability of MOFs in water limits their utility in aqueous systems.…”

• We present an effective catalyst for reductive degradation of organic dyes and phenols in water.• Compared with noble metals, Cu/Cu 2 O/ CuO@C particles are more efficient and less expensive • The porous structure provided a large contact area and channels for the pollutions and active site. , infrared spectroscopy and Raman analysis, revealed that it was composed of graphitized carbon with numerous nanoparticles (100 nm in diameter) of Cu/CuO/Cu 2 O that were uniformly distributed on internal and external surfaces of the carbon support. Gallic acid (GA) has been used as both organic ligand and carbon precursor with metal organic frameworks (MOFs) as the sacrificial template and metal oxide precursor in this green synthesis. The material combined the advantages of MOFs and Cu-containing materials, the porous structure provided a large contact area and channels for the pollutions, which results in more rapid catalytic degradation of pollutants and leads to greater efficiency of catalysis. The material gave excellent catalytic performance for organic dyes and phenols. In this study, Cu/Cu 2 O/CuO@C was used as catalytic to reduce 4-NP, which has been usually adopted as a model reaction to check the catalytic ability. Catalytic experiment results show that 4-NP was degraded approximately 3 min by use of 0.04 mg of catalyst and the conversion of pollutants can reach more than 99%. The catalyst exhibited little change in efficacy after being utilized five times.

“…219 Examples on industrial research also include the Johnson Matthey company, in the same topic of catalysis and materials science. 220 Two patents have been recently filed by this company concerning a MOF compound and its preparation method (WO2013160683A1, filed in 2013), 221 and another method of MOFs manufacture resulting in high surface area compounds (WO2014114948A1, filed in 2014). [222][223][224][225][226][227][228][229][230][231] It is important to emphasize that the thermal stability of MOFs is usually limited to temperatures below 400 ºC, which somehow reduces their potential with respect to applications at high temperatures.…”

“…[22] The high density of exposed metal ions in these materials has sparked much interest in the field of adsorption and the adsorptive separation of compounds such as CO, CO 2 , CH 4 , ethane, acetylene, propane, propylene or H 2 S. [20,[23][24][25][26][27][28][29][30][31] The existence of a family of isostructural materials has also allowed to study the specific role of the metal ion in these adsorption processes.

The hybrid frameworks M 2 dobdc (dobdc 4-= 2,5-dioxidoterephthalate, M 2+ = Mg 2+ , Co 2+ , Ni 2+ , Cu 2+ and Zn 2+ ), commonly known as CPO-27 or MOF-74, are shown to be active catalysts in base-catalyzed reactions such as Knoevenagel condensations or Michael additions. Rather than utilizing Nfunctionalized linkers as a source of basicity, the intrinsic basicity of these materials arises from the presence of the phenolate oxygen atoms coordinated to the metal ions. The overall activity is due a complex interplay of the basic properties of these structural phenolates and the reactant binding characteristics of the coordinatively unsaturated sites. The nature of the active site and the order of activity among the different M 2 dobdc materials were rationalized via computational efforts; the most active material, both in theory and experiment, is the Ni-containing variant. The basicity of Ni 2 dobdc was experimentally proven by chemisorption of pyrrole and observation by IR spectroscopy.
