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 Things

Abstract

This study focus on gas storage based on industrial internet of things. A series of inorganic-organic coordination polymers constructed by lanthanide (III) and asymmetric ligands the pyridine-2,4-dicarboxylate have been prepared in hydrothermal synthesis. The goals of this study were to investigate gas adsorption/desorption behaviors and surface are measurement for samples as-synthesized. These materials possess BET (Brunauer-Emmett-Teller) surface areas about 480-610 m2/g verified by surface area measurement based on N2 sorption at 77 K. The H2 adsorption isotherm at 77 K exhibited stable uptake of 1.35w % both low pressure and high pressure, providing evidence robust framework of compounds with 0.7 nm pore size. Particularly Cerium ion compound shows the highest H2 uptake of 154 cm3/g (1.35 wt %) among of the samples, which is relatively low compared to that of Al-TCBPB and Zn4O (BDC)3, but higher than Zn4O (BTB)2.
