In this research, nanocrystal mesoporous TiOz powders were synthesized by sol-gel method, with TiCl4 as a
precursor in methanol solution. Block copolymer Pluronic PE 6200 was used as pores template. It was found that from
the XRD measurements, both at 400°C and 450°C calcination temperatures, resulted in nanocrystal TiOz with anatase
phase. Based on Nz adsorption characterization (BET method), TiOz samples have surface area 108 mZ/g and 88 mZ/g for
400°C and 450°C calcination temperatures respectively. From Small-angle Neutron Scattering (SANS) patterns, it is
investigated that TiOz samples have mesoporous structure where the pore order degree depend on the calcination
temperature.
