The invention discloses a preparation method, product and application of a MoO 3 /ZnAl layered double hydroxide composite material, comprising: Zn(NO 3 ) 2 ·6H 2 O, Al(NO 3 ) 3 ·9H 2 O and hexamethylenetetramine were dissolved in deionized water to obtain a mixed solution, which was subjected to a hydrothermal reaction, cooled to room temperature, filtered, washed and dried to obtain ZnAl-LDHs; MoO and ZnAl - LDHs were dissolved in ethanol, After ultrasonic dispersion treatment, the MoO 3 /ZnAl-LDHs composite material was obtained by stirring and drying at 80°C. The invention adopts a simple hydrothermal method to synthesize ZnAl-LDHs hydrotalcite, and then obtains a MoO 3 /ZnAl-LDHs composite material by a simple solvent evaporation method. Due to the synergistic effect between the materials, the photocatalytic performance is improved, and the initial concentration within 60 minutes is The removal rate of 50mg/L tetracycline reached 79.3%. |
