Abstract
In the absence of sphere templates, hollow sodailte/NiO composite spheres were obtained by one-pot hydrothermal synthesis by using polyacrylamide hydrogels as "soft template". And the effect of nickel oxide content on the synthesis of hollow complex spheres was studied. The samples were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX). The results showed that when the content of nickel oxide was about 0.5%, the hollow sodalite/NiO composite spheres with high crystallinity, stable crystal, and obvious hollow structure could be successfully synthesized.
