Embodiment 1
[0041] 1) Prepare Ce(NO at a concentration of 0.02mol / L at room temperature 3 )·6H 2 O aqueous solution;
[0042] 2) Add 4mlCe(NO 3 )·6H 2 O aqueous solution, 4m toluene and 2ml H 2 o 2 , into a high-temperature reaction kettle with a sealing device and a liner coated with a layer of tetrafluoroethylene, without any stirring;
[0043] 3) React at 150°C for 2 hours;
[0044] 4) After the reaction is finished, pour off the upper layer solution, and the nano-cerium oxide will directly sink to the bottom of the reaction kettle, and then add ethanol to disperse.
Embodiment 2
[0046] 1) Ce(NO 3 )·6H 2 O aqueous solution;
[0047] 2) Add 12mlCe(NO 3 )·6H 2 O aqueous solution, 14m toluene and 3ml H2 o 2 , into a high-temperature reaction kettle with a sealing device and a liner coated with a layer of tetrafluoroethylene, without any stirring;
[0048] 3) React at 180°C for 36 hours;
[0049] 4) After the reaction is finished, pour off the upper layer solution, and the nano-cerium oxide will directly sink to the bottom of the reaction kettle, and then add ethanol to disperse.
Embodiment 3
[0051] 1) Ce(NO 3 )·6H 2 O aqueous solution;
[0052] 2) Add 24mlCe(NO 3 )·6H 2 O aqueous solution, 24m toluene and 3ml H 2 o 2 , into a high-temperature reaction kettle with a sealing device and a liner coated with a layer of tetrafluoroethylene, without any stirring;
[0053] 3) React at 240°C for 72 hours;
[0054] 4) After the reaction is finished, pour off the upper layer solution, and the nano-cerium oxide will directly sink to the bottom of the reaction kettle, and then add ethanol to disperse.
