عنوان انگلیسی Gas Storage Performance Investigation of {Ln3(2,4-PDCH)(2,4-PDC)4･11H2O}n (Ln=La,Ce,Nd,Sm,Eu) Based on Industrial Internet of Materials
چکیده انگلیسی مقاله The current study focuses on gas storage performance using the industrial internet of materials. A series of inorganic-organic coordination polymers made by lanthanide (III) and asymmetric ligands the pyridine-2,4-dicarboxylate were prepared in hydrothermal synthesis. The goals of this study were to investigate the gas adsorption/desorption behaviors and to measure the surface areas of the as-synthesized samples. These materials possess BET (Brunauer-Emmett-Teller) surface areas of approximately 480-610 m2/g, which is verified by the surface area measurement based on the N2 adsorption at 77 K. The adsorption isotherm of H2 at 77 K exhibited a stable uptake of 1.35w % both at low pressure and high pressure, providing evidence for the robust framework of compounds with 0.7 nm pore size. Especially, the Cerium ion compound shows the highest H2 uptake of 154 cm3/g (1.35 wt %) among other samples, which is relatively low in comparison with that of Al-TCBPB and Zn4O (BDC)3, but higher than that of Zn4O (BTB)2.
