Abstract:A simple fabrication method that involves two steps of hydrothermal reaction has been demonstrated for the growth of α-Fe 2 O 3 @K-OMS-2 branched core−shell nanoarrays. Different reactant concentrations in the shell-forming step led to different morphologies in the resultant composites, denoted as 0.25 OC, 0.5 OC, and 1.0 OC. Both 0.25 OC and 0.5 OC formed perfect branched core−shell structures, with 0.5 OC possessing longer branches, which were observed by SEM and TEM. The core K-OMS-2 and shell α-Fe 2 O 3 we… Show more
