摘要: Abstract The aim of this work was to study the effect that various copolymers and several synthesis conditions may have on properties mesoporous aluminophosphates obtained using AlCl 3 H PO 4 as aluminium phosphorous precursors, respectively under non-aqueous conditions. Poly(styrene-co-allyl alcohol) triblock type were used structure-directing agents in an acidic medium. parameters investigated poly(styrene-co-allyl included stirring time, Al/P mole ratio, time at 40 °C, calcination temperature amount polymer used. resulting materials characterized by nitrogen adsorption −196 °C, X-ray diffraction (XRD), temperature-programmed ammonia desorption (TPD-NH ) transmission electron microscopy (TEM). Mesoporous with surface areas up 540 m 2 /g obtained.
