Nano-sized Ag3PO4 were decorated on TiO2 particles.
Pinecone-liked Ag3PO4/TiO2 prevents aggregation of nano-sized Ag3PO4.
Ag3PO4/TiO2/rGO exhibit superior photocatalytic activity and stability.
TiO2 and rGO promote photogenerated charges separation in Ag3PO4/TiO2/rGO.
Ag3PO4/TiO2/rGO reduces the consumption of noble Ag.
