中文摘要：
利用传统的浸渍法在一种金属有机骨架化合物MIL-101（Cr3F（H2O）2O[（O2C）-C6H4-（CO2）]3·nH2O，n≈25）上负载金属镍，制备了Ni／MIL-101复合材料．通过采用不同的浸渍手段（过量浸渍，等体积浸渍）和不同的还原方法（液相化学还原，固相加氢还原）制得了不同的Ni／MIL-101样品，并考察了这些样品在温和条件（25～100℃，0．01～4MPa）下的储氢性能．结果表明，Ni／MIL-101样品的储氢性能均比MIL-101的储氢性能有所改善．其中，采用过量浸渍和液相化学还原相结合制备的Ni／MIL-101样品的储氢性能最佳，储氢量可达1．02％．
英文摘要：
The traditional impregnation method was used to support nickel ions on the metal-organic framework compound MIL-101 （Cr3F（H20）20[（O2C）-C6H4-（CO2）]3· nH2O, n≈25） for the preparation of a Ni/MIL- 101 composite material. With two ways of impregnation （excessive impregnation and incipient wetness impregnation） followed by two ways of reduction （liquid chemical reduction and solid hydrogenation reduction）, four Ni/MIL-101 samples were obtained. The hydrogen storage capacity of the Ni/MIL-101 samples was measured under mild conditions （25-100 ℃, 0.01-4 MPa）. Compared with the original MIL-101, Ni/MIL-101 had high hydrogen storage capacity because of the Ni particles supported on MIL-101. Among these samples, the sample prepared by excessive impregnation followed by liquid chemical reduction exhibited the highest hydrogen storage capacity of 1.02 % at 100 ℃ and 4.0 MPa.
