Photocatalytic Activity of Titanium Oxide Nano-Networks Fabricated through Organogel Route Using L-Isoleucine-Based Gelator

Abstract

Titanium oxide nano-networks, which have various crystal structures, were fabricated by the sol-gel polymerization in an organogel formed by L-isoleucine organogelator and their photocatalytic activities were evaluated by a methylene blue method. The TiO₂ nano-networks were formed by which the self-assembled nanofibers of the gelator acted as a template, and their crystal structure was controlled by the calcination temperature. The rutile TiO₂ nano-network, which was fabricated at 700℃, showed a good photocatalytic activity.
