Embodiment Construction
[0019] Bi 2 MoO 6 / TiO 2 / RGO composite photocatalyst is made of Bi 2 MoO 6 、TiO 2 Composed with RGO, Bi 2 MoO 6 、TiO 2 And RGO weight ratio is 15:3:3.
[0020] Preparation method of composite photocatalyst:
[0021] 1. Bi 2 MoO 6 Preparation: using hydrothermal synthesis method, 1mmol ammonium molybdate was dissolved in 10mL deionized water, 7mmol bismuth nitrate was dissolved in 5mL deionized water, the bismuth nitrate solution was slowly added dropwise to the ammonium molybdate solution under magnetic stirring, After the dropwise addition was completed, the stirring was continued for 30 min, and the pH was adjusted to 14 during the stirring process. After stirring, ultrasonically disperse for 30 min. The sonicated mixture was charged into a polytetrafluoroethylene-lined stainless steel reactor with a filling degree of 70%, heated to 160°C and kept for 24 hours, and then naturally cooled to room temperature. After the precipitate was washed three times with deio...
