Abstract
The visible-light-active xAgSbO3/NaNbO3 (x=0.5, 1, 2, 4, 6) composite photocatalysts were prepared by a conventional solid-state reaction method. Composition dependences on the structure, optical, surface photoelectronic and photocatalytic properties were investigated. The absorption edge of the composites could be red-shifted increasing the amount of AgSbO3 in comparison with that of NaNbO3. The surface photovoltage response shows the selectivity for the amount of AgSbO3 in the samples. The photocatalytic activities for Rhodamine B degradation exhibit a parabola-like behavior with the amount of AgSbO3. The highest photocatalytic activity is observed on the AgSbO3/NaNbO3 composite due to the better dispersiveness, electron transfer and surface photoelectric properties.
