Abstract

Electrostatic self-assembled Ag2O/TiO2 nanobelts heterostructure was synthesized via simple physical mixing of Ag2O nanoparticles and TiO2 nanobelts. The morphologies and microstructures of Ag2O/TiO2 nanobelt heterostructure were characterized by high resolution transmission electron microscopy. The interface dominated high UV photocatalytic activity and degraded photoluminescence strength of composite catalyst confirmed the heterostructure effect between Ag2O nanoparticles and TiO2 nanobelts. X-ray photoelectron spectroscope provided direct evidence of charge transfer on the heterostructures between them.
