%X The adsorption of H2 and H2NCH2CH2NH2 on the nickel-phosphate-basis molecular sieves VSB-1 and CoVSB-1 was studied. The adsorption of H2 is a supercritical physisorption. The adsorption quantity of H2NCH2CH2NH2 on VSB-1 and CoVSB-1 is larger than that of H2O, C2H5OH and other vapor of organic amines. VSB-1 and CoVSB-1 can adsorb 19.7wt% and 24.3wt% of H2NCH2CH2NH2 respectively. The chemisorption mechanism of H2NCH2CH2NH2 on VSB-1 and CoVSB-1 was verified by using XRD, FT-IR and UV-Vis characterization. The large adsorption quantity of H2NCH2CH2NH2 is caused by the chelation between H2NCH2CH2NH2 and the active sites of Ni and Co in the frameworks of VSB-1 and CoVSB-1.
