Rhombic dodecahedron shaped Ag3PO4 microcrystals were prepared by hydrothermal treatment of as-precipitated Ag3PO4 products. The phase formation and morphology of the synthesized products were characterized by powder X-ray diffraction and field emission scanning electron microscopy. Experimental results revealed that hydrothermal reaction time can effectively influence the formation of rhombic dodecahedron-shaped Ag3PO4 microcrystals. The possible formation mechanism for rhombic dodecahedrons morphology was studied. Moreover, the rhombic dodecahedron-shaped Ag3PO4 microcrystals such as 48 h hydrothermally treated sample exhibited higher catalytic activity than as-precipitated and 12 h hydrothermally treated samples under visible light irradiation for the degradation of methylene blue. The enhanced photocatalytic activities of rhombic dodecahedron-shaped Ag3PO4 microcrystals is attributed to the existence of most exposed {110} facets.
