  • Used commercially available mono- and triamine Jeffamine and Surfonamine surfactants as structure-directing agents.

    • Main Results:

    • Achieved large pore sizes (up to 8.2 nm), high surface areas (632-1030 m²/g), and pore volumes (0.5-2.0 cm³/g).
    • MSU-J possesses fully interconnected 3D mesopores, minimizing diffusion limitations.
    • Synthesis is cost-effective, using inexpensive sodium silicate and single surfactants at near-neutral pH.

    Conclusions:

    • MSU-J mesoporous silica offers a promising alternative to existing materials due to its unique 3D wormhole structure and efficient synthesis.
    • The interconnected pore network enhances diffusion, beneficial for adsorption and catalysis.
    • The cost-effective and environmentally friendly synthesis makes MSU-J materials highly attractive for industrial applications.
