M ost known alternative to fossil fuel energy system is widely researched hydrogen economy in the other name hydrogen energy system [1]. The main obstacle to use hydrogen economy in daily life is to store hydrogen as an energy carrier, safely and economically [2][3]. In order to store hydrogen, compressed and liquid gas systems [4] have been being used but for safely and more profitable storage there are many choices such as, metal hydrides [5], carbon nanotubes [6][7], metal organic frameworks (MOFs) [8] which are needed to be improved. Some target values are set for storing acceptable amount of hydrogen to use in portable systems by US DOE (4.5 wt. % by 2007, 6 wt. % by 2010 and 9 wt. % by 2015) [9] and these target are being cited widely by international community. In order to reach the targets, researchers have been working on alternative storage medias and systems which are safe and widely useful for mobile applications like automobile and portable power systems. Weak forces act a great role 226-4533 ( 1261 ) Fax: +90 (364) in physical sorption (also called as physisorption) in solid hydrogen storage medias and reaches great numbers within low temperatures down to 77K. With common usage areas such like gas sorption [8], gas separation [10], catalyst [11][12]; MOFs have a great sorption ability for hydrogen. For instance, Yaghi and co-workers reported that IRMOF-1, IRMOF-8, IRMOF-11, IRMOF-18 and MOF-177 uptakes hydrogen wt.% 1.32, 1.5, 1.62, 0.89 and 1.25 respectively at 77K and 1 bar [13]. With reticular structure, Cu(II)-arginine complex could be called as a MOF structured complex. Too many MOF structured complex are synthesized by using metal or metal clusters with benzene di-, tri-(or more) carboxylic acids widely but amino acids are not used as building block. Amino acids are used for biological or pharmaceutical applications in general such as vascular effects of dietary of arginine or effects for immunity [14][15]. In addition to other applications, in this work a novel Cu(II)-arginine coordination A B S T R A C T C u(II)-arginine coordination compound was synthesized and characterized by using DSC, DTA, EA, FT-IR, XRD, SEM and EDX analysis techniques and then the hydrogen storage properties were investigated. Hydrogen storage performance of synthesized compound was determined both experimental and theoretically by using Materials Studio which is one of the Molecular simulation software and adsorption measurement equipment. It is found out that the arginine compound uptakes approximately 1.2 wt. % experimentally and 0.8 wt. % theoretically hydrogen in 77K and 100 bars pressure. Also the surface characteristics was calculated and also the possible cites which could uptake hydrogen in a single lattice cell were determined. At the end of this research, in addition to drug and other applications of L-arginine, it is proved that could be used as a part of adsorbent for hydrogen storage application. 02 compound is synthesized and characterized to use for hydrogen storage which is not used before, then...

“…MIL-101(Cr) was synthesized via a hydrothermal method reported by [34] where terephthalic acid (H2BDC, 4 mmol) was added to an alkali solution of tetramethyl ammonium hydroxide (TMAOH, 16 ml) and stirred at room temperature for 10 minutes, then Cr(NO3)3.9H2O (4 mmol) was added to the mixture and stirred for another 20 minutes. The resulting mixture was transferred into a 45 ml Teflon-lined autoclave and heated at 453 K for 24 h. After cooling slowly to ambient temperature, a solution of fine green powder as the major product was obtained with a significant amount of recrystallized H2BDC.…”

Adsorption heat pumps can be used for generating heating, cooling, seasonal energy storage and water desalination applications. Metal-organic frameworks (MOFs) are hybrid porous materials with high surface area and superior adsorption characteristics compared to conventional adsorbents. MIL-101(Cr) has a large pore size with water vapour adsorption capacity up to 1.5 gH2O gads -1 and high cyclic stability thus has the potential to be used in adsorption heat pumps. This work investigates the enhancement of the thermal conductivity and water adsorption characteristics of MIL-101(Cr) using hydrophilic graphene oxide. Two methods have been used to develop MIL-101(Cr)/GrO composites. The first method was through physical mixing between MIL-101(Cr) and GrO while the other was through incorporating the GrO during the synthesis process of MIL-101(Cr). The composites and MIL-101(Cr) were characterized in terms of their structure, water adsorption uptake, BET surface area, particle size, thermal gravimetric analysis, SEM images and thermal conductivity measurements. Results showed that introducing low amounts of GrO (<2%) to the neat MIL-101(Cr) enhanced the water adsorption characteristics at high relative pressure but enhanced the heat transfer properties by 20-30% while using more than 2% of GrO reduced the water adsorption uptake but significantly enhanced the thermal conductivity by more than 2.5 times.

MIL-101 and MIL-101-NH 2 were partially modified to incorporate various functional groups that are capable of forming hydrogen bonds with water. Specifically, MIL-101-NH 2 was partially functionalized with -NHCONHCH 2 CH 3 (-UR2), -NHCOCHCHCOOH (-Mal), or -NH(CH 2 ) 3 SO 3 H (-3SO 3 H) and MIL-101 was partially functionalized with -COOH in order to investigate the effect of these groups on the water sorption properties when compared to the pristine versions. The MIL-101 derivatives were synthesized by either post-synthetic modification of MIL-101-NH 2 or through direct synthesis using a mixed linker strategy. The ratios of the incorporated functional groups were determined by 1 H-NMR analyses and the porosity changes were revealed by N 2 gas adsorption measurements at 77 K. Water sorption isotherms at 298 K conclude that the incorporation of -3SO 3 H enhances the water vapour uptake capacity at a low relative pressure (P/P 0 ¼ 0.30), whereas -UR2 and -Mal retard water adsorption in MIL-101-NH 2 . The partial incorporation of -COOH in MIL-101 exhibits a steeper water uptake at lower pressure (P/P 0 ¼ 0.40) than MIL-101-NH 2 . Interestingly, a greater -COOH content within the MIL-101 framework reduces the water uptake capacity. These results indicate that even partial functionalization of MIL-101 induces noticeably large changes in the water adsorption properties.
