Facile Fabrication and Magnetic Properties of Macroporous Spinel Microspheres from Layered Double Hydroxide Microsphere Precursor

摘要

Macroporous CoFe2O4 spinel microspheres have been fabricated by a simple process involving calcination of layered double hydroxide microsphere precursor, which was originally prepared by spray drying with polystyrene as template. Layered double hydroxides (LDHs) are a class of anionic
