摘要:
It is possible to obtain a visible light-responsive photocatalytic nanoparticle dispersion liquid containing copper-containing titanium oxide nanoparticles by subjecting an aqueous peroxotitanic acid solution containing a copper compound to hydrothermal reaction for crystallizing the aqueous solution by means of heat under high pressure. The visible light-responsive photocatalytic nanoparticle dispersion liquid thus obtained exhibits excellent dispersion stability of titanium oxide nanoparticles within a water-based dispersion medium even when left in a cold and dark indoor area for a long period of time, expresses photocatalytic activity even in visible light (400 to 800 nm) alone, and can easily create a photocatalytic thin film which is extremely transparent and exhibits excellent durability, and in which the state of copper coordination when exposed to heat or ultraviolet rays is stable and cannot be easily modified.
