Copper terephthalate, metal organic framework (MOF) [Cu(BDC)] (H 2 BDC = benzene-1,4-di-carboxylic acid) was synthesized by simple and fast microwave method. Different samples were synthesized by modifying the irradiation time, irradiation power and concentrations of reactants. The samples were characterized by means of FT-IR analysis, X-ray diffraction (XRD), N 2 adsorption/ desorption isotherms, scanning electron microscopy, elemental analysis and thermo gravimetric analysis. The effect of synthesis conditions on crystallinity, crystal size, specific surface area and morphology of the prepared samples were investigated. The XRD patterns of all synthesized samples confirmed the formation of Cu(BDC) without any phase impurities. The samples with the highest Langmuir surface area of 624 and 611 m 2 /g were considered for CO 2 and CH 4 adsorption isotherms. Adsorption isotherms of CH 4 and CO 2 were determined by volumetric method in the range of 0.1-60 bar pressure at normal temperature. The highest adsorption capacity for CO 2 and CH 4 was determined 10.4 and 5.2 mmol/g, respectively at 303.15 K and 47.7 bar equilibrium pressure. The highest & Azadeh Tadjarodi
Nanorods hydroxyapatite, (HAP) Ca10(PO4)6(OH)2 is successfully prepared by water in oil microemulsion using, CaCL2
and H3PO4
(water phase), poly(sodium 4-styrene sulfonate) (PSSS) as template and cyclohexane as oil phase. The nano-structure of the product was studied by means of X-ray diffraction (XRD), Fourier transmission infrared spectrometer (FT-IR), scanning electron microscopy (SEM), and atomic force microscope (AFM). With this system, we could synthesize nano-particles of hydroxyapatite with high crystallinity and least agglomeration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
