Abstract

LaNi 5 is an important material for hydrogen technology. LaNi 5 nanofibers were synthesised for the first time by a sol-gel process via electrospinning in which polyvinylpyrrolidone was used as the spinning aid and lanthanum and nickel nitrate were used as precursors for the synthesis of LaNi 5 nanofibers. X-ray spectrum studies of nanofibers prepared at different calcination temperatures showed a single phase and a hexagonal structure after hydrogen exposure. The temperature of calcination has a direct effect on the morphology and structure of nanofibers. The morphology of long nanofibers before and after calcination was studied by SEM. The high surface area of LaNi 5 demonstrates the capability of nanofibers to serve as effective alloys in hydrogen storage applications.
