•Two kinds of plate-like NaNbO3 were prepared by the molten salt process.•The composites were obtained after heating plate-like NaNbO3 and urea.•The enhanced photocatalytic activities were observed on the composites.•State of carbon nitride and adsorption of oxygen are very important.
Two kinds of plate-like NaNbO3 were separately prepared by the one- and two-step molten salt processes via topochemical micro-crystal conversion methods. Meanwhile, the composite photocatalysts were obtained via heating the mixture of corresponding NaNbO3 powders and urea. Their photocatalytic activities were evaluated from the photodegradation of Rhodamine B under full arc and visible light irradiation of Xe lamp. The sample containing NaNbO3 prepared by the one-step molten salt process and carbon nitride displays the highest activity. The enhancement of photocatalytic activity was attributed to the surface properties and the state of the carbon nitride.
Graphical abstractTwo kinds of plate-like NaNbO3 and their composites were prepared. The sample containing the NaNbO3 prepared by the one-step molten salt process and carbon nitride displays the highest activity which could be attributed to the surface properties and the state of the carbon nitride.Figure optionsDownload full-size imageDownload as PowerPoint slide
