چکیده

Ag2O/TiO2 nanobelt heterostructures have been found to possess high ultraviolet photocatalytic activity, but a poor cycling performance. After a S-doping treatment, the obtained Ag2O/Ag2S2O7/TiO2 heterostructured nanobelts exhibited an enhanced and stable photocatalytic activity under both ultraviolet and visible light irradiation, which was exemplified by photo-degradation of organic pollutants and photocurrent response measurements. Meanwhile, the crystal structure and phase transformation of Ag2O, Ag2S2O7 and Ag2S were studied by XRD and XPS measurements.

PdO/TiO2 and Pd/TiO2 heterostructured nanobelts with enhanced photocatalytic activity.

Heterostructures play an important role not only in the manufacture of semiconductor devices, but also in the field of catalysis. Herein, we report the synthesis of PdO/TiO2 and Pd/TiO2 heterostructured nanobelts by means of a simple co-precipitation method, followed by a reduction process using surface-modified TiO2 nanobelts as templates. The as-obtained heterostructures were characterized by...

UV-visible-light-activated photocatalysts based on Bi2O3/Bi4Ti3O12/TiO2 double-heterostructured TiO2 nanobelts†

Surface engineering of TiO2 nanobelts by the controlled assembly of functional heterostructures represents an effective approach for the synthesis of high-performance photocatalysts. In this study, we prepared a novel Bi2O3/Bi4Ti3O12/TiO2 double-heterostructured nanobelt by depositing bismuth hydroxide onto the TiO2 nanobelt surface. A thermal annealing treatment led to the formation of a Bi4Ti...

Synthesis of scaly Sn3O4/TiO2 nanobelt heterostructures for enhanced UV-visible light photocatalytic activity.

A novel scaly Sn3O4/TiO2 nanobelt heterostructured photocatalyst was fabricated via a facile hydrothermal route. The scaly Sn3O4 nanoflakes can be synthesized in situ and assembled on surface coarsened TiO2 nanobelts through a hydrothermal process. The morphology and distribution of Sn3O4 nanoflakes can be well-controlled by simply tuning the Sn/Ti molar ratio of the reactants. Compared with si...

Visible-light photochemical activity of heterostructured core-shell materials composed of selected ternary titanates and ferrites coated by tiO2.

Heterostructured photocatalysts comprised of microcrystalline (mc-) cores and nanostructured (ns-) shells were prepared by the sol-gel method. The ability of titania-coated ATiO3 (A = Fe, Pb) and AFeO3 (A = Bi, La, Y) catalysts to degrade methylene blue in visible light (λ > 420 nm) was compared. The catalysts with the titanate cores had enhanced photocatalytic activities for methylene blue deg...
