In this work, we report the effect of precursor gel preparation on the microstructural formation of Aluminophosphates (AlPOs) and Silicoaluminophosphates (SAPOs) molecular sieves prepared by ionothermal method using (1-ethyl- and 1-Benzyl-3-methylimidazolium chloride [EMIMCl], [BMIMCl]) as both structure-directing agent and solvent. SAPO-5, AlPO-11, AlPO-41 and AlPO-34 were the resultant molecular sieves. The variation of chemical compositions led to the differences in morphologies and crystal sizes. Their morphologies varied from like-needles shapes to cubic forms. The structures and morphologies were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), infra-red (IR) and thermogravimetric analysis (TGA).
