2.3.2. Preparation of the
ZnCo2O4/Ag3PO4Composites
0.612g AgNO3 was added to 30 ml of silver nitrate
solution, and also ZnCo2O4 (0.1g, 0.2 g,
and 0.3g) was added to the silver nitrate solution, sonicated for 30 min
to disperse ZnCo2O4 evenly, then slowly
added to 30 ml of solution having 0.43g
Na2HPO4·12H2O and
stirred at room temperature for 120 min. After that, the product was
filtered and precipitated by centrifugation, cleaned with deionized
water and anhydrous ethanol, dried at 60 °C, and three
ZnCo2O4/Ag3PO4catalysts with different ZnCo2O4contents were obtained, which were labeled as 0.1
ZnCo2O4/Ag3PO4,0.2
ZnCo2O4/Ag3PO4,
and 0.3
ZnCo2O4/Ag3PO4,
respectively. A single Ag3PO4 was
prepared for comparative study.
