Abstract- Macroporous TiO2 with mesocellular foam structure large spherical cells (diameter size of 24-42 nm) interconnected
was prepared using eggshell membrane as a single template. The by uniform windows (diameter size of 9-19 nm) has attracted
as-synthesized catalyst was characterized by N2 adsorption- much attention. However, the synthesis of MCFs usually needs
desorption analysis, X-ray powder diffraction (XRD) and anic additives which are often toxic [8].
scanning electron microscopy (SEM) analysis. The results
indicate that hierarchical porous structure exists in the as- Titanium dioxide with hierarchical porous structure has
synthesized TiO2 membrane. The mesocellular foam posed been synthesized in this study by sol-gel method using eggshell
of cell with diameter of about 20 nm and smalle
