Abstract

Hollow Fe<inf>x</inf>Ni<inf>(1−x)</inf>OOH nanospheres with average diameter and shell thickness of about 15 and 5 nm were successfully synthesized for the first time through the radiation induced self-template method. The fast outward diffusion of Fe(III) ions due to Kirkendall effect between the core (FeOOH) and the shell (Fe<inf>x</inf>Ni<inf>(1−x)</inf>OOH) is the main reason for appearing the hollow nanoparticles. The results showed that a passive layer of Fe(III) species was formed at core and shell interface and Ni(II) ions play an important role in hollowing process of nanoparticles.
