A photocatalytically inactive microporous titanate nanofiber as an excellent and versatile additive to enhance the TiO2 photocatalytic activity

Abstract

The photocatalytic activity of TiO₂ under simulated solar light, evaluated by the oxidative decomposition of organic compounds in water, was substantially enhanced when a new and photocatalytically inactive TiO₂-based nanostructured material (a microporous titanate nanofiber) was just mixed with the starting suspension, as a result of the unique electron capture ability of the titanate to retard charge recombination.
