Effect of carbonization temperature on adsorption property of ZIF-8 derived nanoporous carbon for water treatment, Microporous and Mesoporous Materials (2016), doi: 10.1016/j.micromeso.2016 This is a PDF file of an unedited manuscript that has been accepted for publication.

AbstractThe heat treatment effect on the adsorption capabilities of nanoporous carbon particles derived from Zeolitic Imidazolate Framework-8 (ZIF-8) was investigated at 600, 1000 and 1200 C in this study. The results showed that heat treatment at 1000 C had a significant effect on the adsorption capacity of ZIF-8 (almost 10 times) for the removal of methylene blue (MB) dye from water. Nanoporous carbons were synthesized by direct carbonization of ZIF-8. SEM and TEM images showed that the carbon resulting from ZIF-8 carbonization at various temperatures retained the original structure and morphology of ZIF-8. The carbon nanoparticles carbonized at 1000 C exhibited outstanding adsorption capacities (186.3 mg/g) compared to nanoparticles carbonized at 600 C (49.5 mg/g) and 1200 C (36.7 mg/g) as wellas ZIF-8 (19.5 mg/g) due to the change in surface charge and pore size distribution. The surface functionalities of materials were also characterized by Raman Spectroscopy, N 2 M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT2 adsorption-desorption, FTIR and TGA. The surface charge of the carbon particles changed from positive (ZIF-8) to negative as a result of conversion to carbon confirmed by zeta potential of the samples. The ZIF-8 derived carbon nanoparticles were found to be efficient adsorbents for water treatment purposes due to the satisfactory adsorption properties such as high adsorption capacity and good wettability.

In this study, a clew-like ZnO superstructure was synthesized by a copolymer-controlled self-assembly homogeneous precipitation method. Ni was impregnated to the clew-like ZnO superstructure to obtain Ni/ZnO adsorbents. The synthesized materials were characterized by scanning electron microscopy, transmission electron microscopy, N 2 sorption, X-ray diffraction, Fourier transform infrared spectrometry, and H 2 -temperature programmed reduction techniques. The reactive adsorption desulfurization (RADS) performance of the adsorbents was evaluated in a fixed bed reactor using thiophene in n-octane as a model fuel. Sample Ni/ZnO-4h exhibits a remarkably high performance with a sulfur capacity of 189.1 mg S g -1 , which is above 6 times that of the one prepared with commercial ZnO. Characterization results show that the morphology changes from micro-clews to large solid sticks with the increase of the crystallization time.The loose and open architecture of the clew-like ZnO superstructure facilitates the diffusion of reactants/products, and prevents the adsorbent particles from breakage by supplying space for the volume expansion during the RADS process. The small nanoparticles in ZnO nanostrips result in a high sulfur adsorption capacity and also favor the dispersion of Ni, leading to an excellent RADS performance.

“…And adsorption desulfurization is recognized as one of the most promising methods to break out the limitations with the traditional hydro-desulfurization process [2].Metal-organic frameworks (MOFs) are a class of materials assembling both polydentate organic ligands and inorganic ions building blocks into a uniform framework by self-assembly [3]. They possess excellent adsorption properties for thiophenic compounds because of their huge variety of structures, large surface areas, ultrahigh porosity and high functionality.And MOF-5 is one of the most porous MOFs because of high specific prominentrepresentatives of these 3Darea and thermal stability [4].…”

A series of transition metal-doped MOF-5 materials (M-MOF-5, M=Cu, Co or Mn) have been prepared by hydrothermal methodology. The structures of M-MOF-5 were confirmed by powder X-ray diffraction (XRD) and Fourier transform infrared (FT-IR). The adsorptive performance of thiophenic compounds (T, BT and DBT) with metaldoped MOF-5 materials was investigated using static adsorption method. Desulfurization capability of Cu-MOF-5 has been an appreciable increase in comparison with the MOF-5. The center metal of MOF-5 has an influence on their surface properties which causing an impact on the adsorption properties.
