The main goal of this work was to develop a cheap and easy method for the synthesis of the porous metallosilicate macrospheres. Zirconium silicate macrospheres with diameters in the range 1.5 – 1.6 mm were obtained by the spray gelling technique, using the multi templating method. Tetraethyl orthosilicate was used as silica source. The chitosan played a dual role (pore and shape generating agent), while other inexpensive and easily accessible biomaterials including yeast, sugar and gelatin...
