Abstract	Nanocomposite of Mn$_{2}$O$_{3}$/Al$_{2}$O$_{3}$/SiO$_{2}$ was prepared through an in situ sol–gel process, in which Mn$_{2}$O$_{3}$ nanocrystals were dispersed in the silica-alumina amorphous matrix. The synthesized products were studied by X-ray diffraction, thermogravimetric and differential thermal analysis, Brunauer–Emmett–Teller surface area analysis, UV–Vis spectroscopy and transmission electron microscopy. The nanocomposite was applied as a novel adsorbent for removal of methylene blue dye and the effect of heat treatment and contact time were studied. The results showed that nano-Mn$_{2}$O$_{3}$ particles were distributed on the surface of Al$_{2}$O$_{3}$/SiO$_{2}$ and formed an activated surface charge. In addition, it was found that the nanocomposites removal rate strongly depended on the heat-treatment of absorbent.
