1. The method of AgFeO preparation is based on co-precipitation/
hydrothermal of Fe2(SO42)3 and AgNO3 in the presence of glycerol.
2. Schematic representations of all the steps were represented in Fig. 1A.
3. Typically, 1 mmol of Fe2(SO4)3 and 1 mmol AgNO3 were mixed together
in 30 mL deionized water with 3 mL glycerol.
4. Then, 10% of NaOH was added with stirring for about 1 h.
5.The precipitate was transferred to a Teflon autoclave and was heated at 180 °C for 24 h.
6. The precipitate was cooled and separated using a magnet and washed several times
by deionized water.
