Bi4Ti3O[Formula: see text]/Bi2S3 heterostructures with enhanced visible light photocatalytic activity are successfully synthesized via a two-step synthesis route based on a sol–gel hydrothermal method and a subsequent hydrothermal-ion exchange reaction technique. The structures, composition, morphologies and light absorption capability of Bi4Ti3O[Formula: see text]/Bi2S3 heterostructures are verified by XRD, XPS, SEM, TEM and UV-Vis diffuse reflectance spectra, respectively. Results indicated that Bi2S3 nanorods are grown on the surface of the spherical structure assembled by criss-cross nanosheets of Bi4Ti3O[Formula: see text] after ion exchange reaction. The photocatalytic tests reveal that the Bi4Ti3O[Formula: see text]/Bi2S3 heterostructures showed much higher photocatalytic activity than pure Bi4Ti3O[Formula: see text] or Bi2S3. The tight interconnection between the two semiconductors will facilitate the photoinduced carriers’ separation. Owing to the easy preparation and excellent property, the obtained Bi4Ti3O[Formula: see text]/Bi2S3 heterostructures may be promising photocatalysts for practical application.

The photocatalytic activity of the layered perovskite K2La2Ti3O10 was regulated by an ion-exchange reaction with a series of cations – Ca2+, Sr2+, and Ba2+. The underlying mechanism of the improved performance and an effective model for designing the photocatalyst were discussed.

Ion Exchange Reaction

The formation of reactive oxygen species due to irradiation by a visible light of the polythiophene deposited in ZSM-5 zeolite channels in aqueous medium has been studied. Polymerization of thiophene was carried out in zeolite channels after the ion-exchange reaction of Na+ for Fe3+. By means of EPR spectroscopy, the temporarily generated 1O2 in irradiated aqueous medium was proved. The formation of O2-• was confirmed by the reduction of Fe3+-cytochrome c. Irradiation led to the water reduction to hydrogen.
