Melting nitrates in non-polar solvent: a new method for fabrication of multicomponent mesoporous ferrites via nanocasting

A series of ordered mesoporous single phase Cu1-xZnxFe2O4 spinel ferrites, with x ranging from 0.00 to 0.75 with a step increment of 0.25, are prepared by a novel nanocasting route with the aid of vinyl-functionalizedmesoporous silica as a hard template. All samples display a relatively high surface area and narrow pore size distribution from nitrogen sorption analysis. The magnetic hysteresis loops of these samples measured at 300 K, show the presence of superparamagnetic nanoparticles in all samples.
