文摘

A nine-connected metal鈥搊rganic framework [Ni^II₂Ni^III(渭₃-OH)(IN)₃(BDC)_1.5]路xSolvent (BDC = benzene-1,4-dicarboxylate, IN = isonicotinate) has been prepared and characterized. The application of the scale-down chemistry through the use of the short and inexpensive BDC and IN ligands leads to a smaller pore size and lower surface area but little compromise in H₂ sorption properties. The compound exhibits a high CO₂ uptake of 73.1 cm³ g^鈥? (273 K and 1 atm) despite its moderate Langmuir and BET surface areas (888.3 and 571.0 m² g^鈥?, respectively). Its H₂ uptake (1.47 wt % at 77 K and 1 atm) is also quite high, comparable to that of many materials with high surface area.
