摘要：

This article describes the synthesis of four porous polymers containing Ni-porphyrin units with Brunauer-Emmet-Teller (BET) specific surface areas up to 1711 m(2)/g achieved. The isotherm gas adsorptions of hydrogen, methane and carbon dioxide over these polymers were measured. The adsorption selectivity for methane and carbon dioxide over nitrogen were also investigated. While the initial isosteric heat of adsorption (Delta H-ads) was around 8-9 kJ/ mol for hydrogen, it reached 23 kJ/mol for methane and 29 kJ/mol for carbon dioxide. CO2/N-2 selectivity as high as 19 (calculated from single gas adsorption isotherms) was also achieved with one of these four polymers.
