Abstract
The visiblelightactive xAgSbO3/NaNbO3 x=05 1 2 4 6 composite photocatalysts were prepared by a conventional solidstate reaction method Composition dependences on the structure optical surface photoelectronic and photocatalytic properties were investigated The absorption edge of the composites could be redshifted 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 parabolalike 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
