We find the stabilization effect of surface capping on the adsorption capacity and photocatalytic activity of Ag3PO4 in the recycling. The citrate anion complex (CAC) as the surface capping is confirmed to be constituted by citrate anion and silver citrate complex. The adsorption capacity of Ag3PO4 with CAC capping exhibits little increase in the subsequent cycle, whereas the one of the bare Ag3PO4 decreases by 25.8% for methylene blue (MB). The photocatalytic activity of Ag3PO4 with CAC capping is maintained, compared to marked 10% decrease of bare Ag3PO4 for degrading MB.
Graphical abstractThe role of the citrate anion complex (CAC) as a surface capping in stabilizing the adsorption and photocatalytic activity of Ag3PO4 during recycling is reported. The stabilization effect is represented by maintaining only a small increase in adsorption capacity, suppressing a large decrease of photocatalytic activity during the recycling process, compared to the sharp decrease of adsorption and photocatalytic activity of bare Ag3PO4.Figure optionsDownload full-size imageDownload as PowerPoint slide
