Cationic surfactant, cetyltrimethylammonium bromide (CTAB) and nonionic surfactant (Triton-X100) was proposed for this experiment. The synthesis of MCM-48 under room temperature condition and hydrothermal heating was conducted using cationic and mixed cationic-nonionic surfactants respectively. The aim of both syntheses was to obtain MCM-48 particles with uniform spherical morphology in narrow nanosized range as well as standard properties of MCM-48 which are high surface area, well-ordered cubic structure, narrow pore size range (2−10 nm) as well as intermediate porosity. These properties were revealed by several analytical tools employed such as FESEM, FTIR, DLS and BET. © 2016 N.A Mokri et al. Published by Elsevier Ltd.

Introduction Siliceous mesoporous MCM-48 is simply described as highly intertwining branches of porous channels in cubic gyroidal (Ia3d) symmetry. This unique feature has enormously attracted attention among researchers as compared to other members, MCM-41(p6mm, hexagonal) and MCM-50(p2, non-stable lamellar structure). It * Nurul Afiqah Mokri.
