MOFs (Metal-Organic Frameworks) and PCPs (porous coordination polymers) are a class of crystalline microporous hybrid solids built of inorganic units (isolated cations, clusters, chains, or layers) connected through polytopic linkers (e.g. polycarboxylate), defining pores of various shapes and sizes. The potential applications of these hybrid solids lie in the area of gas storage and separation, water, air and fuel purification, catalysis, drug release, supercapacitors, and electrochemistry. Compared to their purely inorganic counterparts (zeolites), the great variety offered by the organic chemistry allows the systematic modification of their chemical composition, of their pores surface and, thus, finally, of their properties (very large surface area, sorption selectivity).
The focus of this Special Issue is on a description of recent potential and emerging applications of MOFs and PCPs, and also on recent advances of their uses as catalysts, biorelevant and sensing species, and in toxic gas removal. Articles describing relationships between molecular parameters and structures, preferred adsorption sites, and properties elucidated by using modern theoretical methods are welcome.

Title: Adsorption Behavior of High Stable Zr-based MOFs for Removal of Acid Organic Dye from Water

Abstract: In our work, highly porous metal-organic framework (UiO-66) was successfully synthesized and applied to removal acid orange 7. The adsorption behaviour and mechanism were discussed by the adsorption kinetics, adsorption isotherm as well as adsorption thermodynamics in detail. We can find that the adsorption is a spontaneous process on thermodynamics, and obey pseudo-second order kinetic model. The adsorption isotherm study reveals that the adsorption is well fitted by Langmuir isotherm model with monolayer adsorption, and the maximum adsorption capacity of this MOF material for AO7 is estimated up to be 358 mg g-1 at 318 K. Finally, the Lewis acid-base interaction between AO7 and UiO-66 is verified, in which the zirconium ions as open active site can coordinate with sulfosalt containing in AO7. The strength with the Lewis acid-base interaction of Zr-(-SO3-) is higher than Zr-(H2O) / Zr-(DMF) but less than Zr-(-CO2-). So, UiO-66 not only can effective remove AO7 from water and maintain the complete crystal structure. The zirconium ion with Lewis acid character in UiO-66 is encompassed with water molecule, because a lot of water molecule competes with AO7 molecule to impede the formation of complex between UiO-66 and AO7 during the initial period. Over time, the AO7 molecule spread to the surface of UiO-66, and replace the water molecule to form relatively stable complex compound.
