Embodiment 1
[0026] Ce(NO 3 ) 3 , KCl and LiCl were mixed in a ratio of 2:50:30, and ground with an agate mortar to obtain a uniformly mixed solid mixture; the obtained mixture was collected in an alumina crucible and then put into a muffle furnace, and pressed The temperature was raised to 540°C at a rate of 5°C / min, roasted for 4 h, and cooled naturally; the reacted product was soaked in deionized water to desalinate, and filtered with suction to obtain a yellow solid; the obtained yellow solid was taken out to a centrifuge tube and used to Centrifuged and washed several times with deionized water, dried in vacuum at 60°C to obtain yellow CeO 2 nanoparticles.
[0027] XRD test results show that the product is pure phase CeO 2 compound ( figure 1 ), the results of scanning electron microscopy showed that ( figure 2 ), the synthesized CeO 2 The nanoparticle samples have uniform morphology and good dispersion, with diameters ranging from 60 to 100 nm.
Embodiment 2
[0029] Will Ce 2 (CO 3 ) 3 , KCl and LiCl were mixed in a ratio of 2:50:30, and ground with an agate mortar to obtain a uniformly mixed solid mixture; the obtained mixture was collected in an alumina crucible and then put into a muffle furnace, and pressed The temperature was raised to 660°C at a rate of 5°C / min, roasted for 4 h, and cooled naturally; the reacted product was soaked in deionized water to desalinate, and filtered with suction to obtain a yellow solid; the obtained yellow solid was taken out to a centrifuge tube and used to Centrifuged and washed several times with deionized water, dried in vacuum at 60°C to obtain yellow CeO 2 nanoparticles.
[0030] image 3 It is the CeO prepared in this example 2 Scanning electron micrograph of the sample, it can be seen that the synthesized product CeO 2 It is a spherical nanoparticle with a diameter of 100-400 nm.
Embodiment 3
[0032] Will Ce 2 (CO 3 ) 3 , KCl and LiCl were mixed in a ratio of 2:50:30, and ground with an agate mortar to obtain a uniformly mixed solid mixture; the obtained mixture was collected in an alumina crucible and then put into a muffle furnace, and pressed The temperature was raised to 780°C at a rate of 5°C / min, roasted for 3 h, and cooled naturally; the reacted product was soaked in deionized water to desalinate, and filtered with suction to obtain a yellow solid; the obtained yellow solid was taken out to a centrifuge tube and used to Centrifuged and washed several times with deionized water, dried in vacuum at 60°C to obtain yellow CeO 2 nanoparticles. Figure 4 It is the CeO prepared in this example 2 Scanning electron micrograph of the sample, it can be seen that the synthesized product CeO 2 It is a spherical nanoparticle with a diameter of 600-1000 nm.
