Preparation of Bi2Ti2O7/TiO2 nanocomposites and their photocatalytic performance under visible light irradiation

The octahedral Bi2Ti2O7 nanoparticles have been successfully supported on TiO2 nanotubes (BTO/TiO2 NTs), which exhibit a markedly enhanced photocatalytic activity and good stability for degradation of organic pollutants under visible light irradiation.172
