【 摘 要 】

The aim of this research is to know the influence of Li+ doping into [Cu3(BTC)2] (BTC: benzene 1,3,5-tricarboxylate) or called as Hongkong University of Technology-1 (HKUST-1) structure through ex-situ modification under the solvothermal condition and testing for hydrogen storage. The HKUST-1 structure remains stable after Li+ doping with variation 3, 5, and 10 wt.%, according to XRD analysis, however surface area of HKUST-1 changes significantly up to 1040.96 m2/g after doped with 5 wt.% of Li+ and gave impact to the hydrogen uptake. At temperature 30°C (1.4 bar), hydrogen uptake of Li+ @HKUST-1 reached up to more twice than HKUST-1 without Li+. In addition, the presence of Li+ also increases hydrogen uptake at high temperature (80°C, 1.4 bar). Hydrogen uptake enhancement after doping with Li+ could be due to Li+ supplies additional active site to bind hydrogen molecules.
