Figure S1 showed TEM and SEM images and electron diffraction patterns recorded 11 

on pine tree shape, chromosome shape, hex-cross shape, and spinning-top shape of 12 

Ag3PO4 crystals, respectively. The results demonstrated the controlled growth of 13 

vertically aligned Ag3PO4 crystals in the [100] orientations. The similar controls have 14 

also been achieved over the orientation of Ag3PO4 crystals. Furthermore, the 15 

structures of Ag3PO4 crystals always remained the same cubic phase when Ag3PO4 16 

crystals grew under different reagents. 17

Figure S1. The TEM and ED images of the Ag3PO4 crystals synthesized under different 26 

addition reagents: (a) no reagent; (b) 1 g/L of Triton-100; (c) 1 g/L of polyglycol-400; (d) 1 27 

g/L of sodium polyacrylate. 28

The approximate absorption spectra in the FT-IR spectra provided an accessorial 30 

explanation that the products had the same crystal structure. The corresponding FT-IR 31 

spectrum of the products was shown in Figure S2. The spectrum bands at 3435, 2350, 32 

1635, 1390, 1015 and 560 cm-1 were assigned to water ν1(H-O-H) antisymmetric 33 

bending mode, water-phosphate H bonding, ν2(PO43-) antisymmetric stretching mode, 34 

ν3(PO43-) symmetric stretching mode and ν3(PO4

3-) in-phase P-O bend [S1] 35 

respectively. 36

sodium polyacrylate. 40

Their Raman spectra were shown in Figure S3. Raman scattering was a powerful 41 

tools for observing the synthesis of Ag3PO4 crystals under different organic addition 42 

reagents. The absorption bands at 500 and 720 cm-1 were attributed to P-O bending 43 

and stretching vibration. The absorption band within 200-250 cm-1 was the H-O-H 44 

stretching broad. 45

Figure S4 displayed the N2 adsorption/desorption isotherms of the Ag3PO4 crystals 53 

under different addition reagents. The Ag3PO4 crystals under different addition 54 

reagents exhibited the type II adsorption isotherm without prominent rise at p/p0 < 0.1 55 

and with a marginal hysteresis at p/p0 > 0.9. The BET surface area was evaluated to 56 

be 1.5, 1.2, 16.6 and 15.6 m2/g for Ag3PO4 crystals under the different condition, (a) 57 

no reagent; (b) 1 g/L of Triton X-100; (c) 1 g/L of polyglycol-2000; (d) 1 g/L of 58 

sodium polyacrylate, respectively [S2]. 59
