| 摘 要： | 采用溶剂热法制备了纳米金属有机框架材料,通过粉末x射线衍射(PXRD)、高分辨透射电镜(HRTEM)、红外光谱(FT-IR)、热重分析(TG)、差示扫描量热法(DSC)和压力-组成-温度测试仪(PCI)等分析和表征手段,获得了该材料结构、形貌、热稳定性和吸附性能等信息.该材料对不同吸附质(如水0.19 g/g和苯0.41 g/g),表现出不同的吸附能力,并具有双亲功能.在77 K,1.5 MPa条件,其储氢量为3.2%(质量分数,下同),包含微孔内填充的高压氢气时为3.4%,包含中孔、微孔内填充的高压氢气时为3.9%.

| Abstract: | . The nano-scale metal organic frameworks (Nano-MOF) were synthesized under solvothermal conditions (N, N-dimethyllformamide, DMF)and characterized by PXRD, HRTEM, FT-IR, TG, DSC, PCI, and etc., to obtain relevant information of structures, morphologies, thermal stability and adsorption capabilities. The adsorption measure-ments of various guest molecules on Nano-MOF were also carried out, showing high adsorption capacity. 0.19 g/g for wa-ter and 0.41 g/g for benzene were adsorbed on Nano-MOF, indicating both the hydrophilic and hydrophobic properties of the framework. The hydrogen storage capacity of the framework at 77 K, 1.5MPa was 3.2% ( mass fraction, similarly hereinafter) (3.4% with H2filled in micropores and 3.9% with H2filled in micropores and mesopores). |
