Abstract

Abstract: Aquarternary hydrogen storage alloy LaNi₄Cu_0.5Co_0.5 was prepared using a copre-cipitation-reduction diffusion method. The alloy is activated easily. The surface species and composition of the alloy were derived from XPS measurements. SEM studies revealed many microcracks formed after activation, favoring rapid hydrogen absorption kinetics.

Key words: hydrogen storage material, La Ni Cu Co alloy, preparation, property, coprecipitation-reduction diffusion method, XPS, activation
