Example Embodiment
[0015] Embodiment 1: The preparation process and steps in this embodiment are as follows:
[0016] (1) Weigh accurately 2.0200g Fe(NO 3 ) 3 ·9H 2 O, 2.4254g Bi(NO 3 ) 3 ·5H 2 O and 5.9498g Zn(NO 3 ) 2 ·6H 2 Put O in a beaker, add 100 mL of deionized water, and stir to completely dissolve it. (2) Add 1.1261g of glycine, keep 70°C constant temperature water bath with magnetic stirring to make it fully complex, and evaporate to obtain a viscous colloid. (3) Dry the obtained colloid in an ordinary oven at 100°C under air atmosphere for 12 hours to obtain a dry gel, and then calcinate it in a muffle furnace at 500°C for 3 hours to obtain a pure phase Bi 25 FeO 40 / ZnO photocatalyst sample.
