Synthesis of mesoporous TiO2 in aqueous alcoholic medium and evaluation of its photocatalytic activity

▶ Mesoporous TiO2 synthesized using P123 as soft template in sol-gel method. ▶ Nanoparticle aggregates are better for photocatalytic activity than free nanoparticles. ▶ Particle to particle transport of electrons in the conduction band of aggregates are important factor.
