Low temperature curable titanium-based sols for visible light photocatalytic coatings for glass and polymeric substrates

Abstract

Titanium oxide (TiO2) is a widely used material in photocatalytic coatings in which efficiency generally lies in the ultraviolet (UV) spectrum of light. Sol-gel method provides a simple and versatile...

Unravelling co-catalyst integration methods in Ti-based metal–organic gels for photocatalytic H2 production

“…This suggests a competitive interaction between visible and UV photons in the generation of photocharges, impacting catalytic activity. In this sense, previous works on Ti-based metal–organic materials have demonstrated that these types of photocatalysts can perform either better or worse under visible irradiation with respect to UV–visible illumination depending on the defects 18 and could even be active only under visible light, 60 which should also be taken into account for further photocatalyst development.…”
