Nanocrystalline meso-TiO2 also has been synthesized with hexadecylamine template for comparison through known procedure. The meso-TiO2 materials were characterized by X-ray diffraction, FT-IR, UV-Vis absorbance spectra, thermal analysis, SEM, HRTEM and textural properties through N-2 adsorption-desorption isotherms. Spherical shape particles in a range of few hundred nanometers are obtained in the template free method. Above systematic characterization provides direct indications toward the mechanism of formation of meso-TiO2 in the template free method. A comparison of the physical and textural properties indicates a possibility of coarse-tuning of the textural characteristics of mesoporous TiO2 by adopting different preparation methods.</p>10aMesopore10aMesopore Formation10aTemplate-Free10aThick Wall10atitania1 aKulkarni, Dhanashree, G.1 aMurugan, Vadivel1 aViswanath, Annamraju, Kasi1 aGopinath, Chinnakonda, S.  uhttps://library.ncl.res.in/content/template-free-synthesis-mesoporous-tio2-high-wall-thickness-and-nanocrystalline-framework-0
