Mesoporous titanium dioxide (TiO 2 ) with a pore size range from 5–7 nm was synthesized by a sol‐gel method using biosurfactant phosphatidylcholines as an organic template. Titanium tetrabutoxide (TBOT) was used as the precursor. A very fine mesoporous structure formed in the particle was maintained after a heat treatment at 700 °C. Low‐angle X‐ray powder diffraction (XRD) and a pore size distribution curve revealed the existence of the mesoporous structure. Transmission Electron Microscopy (TEM) and N 2 adsorption–desorption isotherms were utilized for further characterization. A significant red shift in the UV‐VIS spectrum of the porous material was observed, which could be explained by the energy band theory. The results confirmed the synthesis of mesoporous TiO 2 .
