Nano-composite of Fe-doped anatase TiO{sub 2} nanocrystals loaded on the hollow glass microbeads was prepared by co-thermal hydrolysis deposition and calcining treatment. The adherence of TiO{sub 2} mesoporous layers to the surfaces of hollow glass microbeads prevented the aggregation of TiO{sub 2} nanoparticles and benefited to their catalytic activity. The doping of Fe ions makes the absorption edge of the TiO{sub 2} based nano-composite red-shifted into the visible region. An effective photodegradation of the methyl orange aqueous solution was achieved under visible light (lambda>420 nm) irradiation, revealing the potential applicability of such nano-composite in some industry fields, such as air and water purifications. - Graphical abstract: Nano-composite of Fe-doped anatase TiO{sub 2} nanocrystals loaded on the hollow glass microbeads was prepared by co-thermal hydrolysis deposition.
