| Summary: | 碩士 === 逢甲大學 === 化學工程學所 === 94 === Hydrogen storage alloys of magnesium and nickel were synthesized by polyol process with ethylene glycol as reducing agent and polyvinylpyrrolidone （PVP）as dispersing agent. At a concentration ratio of 3:2 （0.03 mol magnesium acetate and 0.02 mol nickel acetate）， the mean particle size is 72.1 nm by dynamic light scattering（DLS）; the closely spaced redox peaks are 0.40 V and 0.25 V by cyclic voltammetry （CV）， relative to Ag/AgCl reference；XRD results show peaks of Mg2Ni、Mg、and Ni with 32% Mg and 50% Ni from analysis of inductively coupled plasma（ICP）; and the hydrogen storage capacity was found to reach 0.8~1.5 wt%. The results show the potential of low cost manufacture of metal hydrides by polyol process.
