Embodiment 1
[0016] 0.1498g Ce(NO 3 ) 3 .6H 2 O was dissolved in 20mL ethanol, and 352uL n-butyl titanate was dissolved in a mixture of 20mL ethanol and 10mL deionized water. The above two solutions were mixed and dispersed uniformly under ultrasonic conditions, and then the mixed solution was charged into a 100 mL hydrothermal reaction kettle, and reacted at 120°C for 48 hours. After the reaction was completed and the system was lowered to room temperature, the solid obtained from the reaction was collected by centrifugation, washed alternately with deionized water and ethanol, and dried overnight at 60°C. Finally, the obtained material was calcined at 450°C for 5h with a heating rate of 5°C / min-1.
Embodiment 2
[0018] 0.1498g Ce(NO 3 ) 3 .6H 2 O was dissolved in 20mL ethanol, and 117uL n-butyl titanate was dissolved in a mixture of 20mL ethanol and 10mL deionized water. The above two solutions were mixed and dispersed uniformly under ultrasonic conditions, and then the mixed solution was charged into a 100 mL hydrothermal reaction kettle, and reacted at 120°C for 48 hours. After the reaction was completed and the system was lowered to room temperature, the solid obtained from the reaction was collected by centrifugation, washed alternately with deionized water and ethanol, and dried overnight at 60°C. Finally, the obtained material was calcined at 450°C for 5h with a heating rate of 5°C / min-1.
Embodiment 3
[0020] 0.1498g Ce(NO 3 ) 3 .6H 2 O was dissolved in 20mL ethanol, and 587uL n-butyl titanate was dissolved in a mixture of 20mL ethanol and 10mL deionized water. The above two solutions were mixed and dispersed uniformly under ultrasonic conditions, and then the mixed solution was charged into a 100 mL hydrothermal reaction kettle, and reacted at 120°C for 48 hours. After the reaction was completed and the system was lowered to room temperature, the solid obtained from the reaction was collected by centrifugation, washed alternately with deionized water and ethanol, and dried overnight at 60°C.
