Abstract

In this paper, we developed low molecular weight gel system based on cholesterol derivative containing pyridine unit attached through β-alanine linkage, which can act as efficient gelator to form novel gel systems in organic or organic–water solvents. Spherical nanoscale anatase–TiO₂ with porous structure was obtained through the In situ hydrolysis in the gel tissue upon the instant addition of water followed by calcination, which had photo catalytic activity toward naphthol blue black. To the best of our knowledge, this is the first example that cholesterol-based gel tissue was employed as the template to construct TiO₂ with photo-catalytic activity.
