| Summary: | 碩士 === 逢甲大學 === 化學工程學所 === 95 === In this study, hydrogen storage alloys of magnesium and nickel were synthesized by polyol process with ethylene glycol as reducing agent and polyvinylpyrrolidone （PVP）as dispersing agent. Finally added palladium chloride at 180 K to obtain alloys. Under high temperature and pressure, hydrogen will diffuse into the alloys. Hydrogen within the alloys will be trapped after the temperature and pressure go back to normal. On reheating the system, hydrogen will be released from within the alloys. We can approval when the proportion of magnesium and nickel was 4：1 the hydrogen stored quantity can achieve to 3.63%, it was higher than the hollow silica microsphere. The Mg2Ni alloys due to its high hydrogen absorption capacity, safety and low cost is considered as a promising candidate for hydrogen storage applications.
