Embodiment 1
[0032] The invention describes the use of formate and carbonate as raw materials to synthesize CeO by hydrothermal method 2 nanotube approach. First, weigh 1.0g Ce(NO 3 ) 3 ·6H 2O was dissolved in 24.5 ml of deionized water to form a clear solution. Under vigorous stirring, 2 ml of formic acid was added to the above solution and mixed well to form a solution. Add 3.5ml of ammonia water to the mixed solution, and mix evenly to form a suspension. Finally, 0.6g of sodium bicarbonate was added to the suspension, transferred to a closed reaction kettle, placed in an oven, and heated at 120°C for 20 hours. After the reaction, the resulting precipitate was filtered, washed with distilled water, and dried to obtain a compound with carbonate and formic acid. Root CeO 2 Nanotube precursor, its electron microscope picture is as follows figure 1 and figure 2 , infrared spectrum such as image 3 , the thermogravimetric curve as Figure 4 . The precursor was heated at 450° C. fo...
Embodiment 2
[0034] Weigh 1.0g Ce(NO 3 ) 3 ·6H 2 O was dissolved in 24 ml of deionized water to form a clear solution. Under vigorous stirring, 2 ml of formic acid was added to the above solution and mixed well to form a solution. Then add 4ml of ammonia water to the mixed solution, and mix evenly to form a suspension. Finally, 0.6g of sodium bicarbonate was added to the suspension, transferred to a closed reaction kettle, placed in an oven, and heated at 120°C for 20 hours. After the reaction, the resulting precipitate was filtered, washed with distilled water, and dried to obtain an anisotropic structure. CeO 2 Nanotube precursors. The precursor was heated at 450° C. for 5 hours under air flow to obtain a pale yellow sample. After washing and drying, pure CeO was obtained 2 nanotube.
Embodiment 3
[0036] Weigh 1.0g Ce(NO 3 ) 3 ·6H 2 O was dissolved in 24.5 ml of deionized water to form a clear solution. Under vigorous stirring, 2 ml of formic acid was added to the above solution and mixed well to form a solution. Add 3.5ml of ammonia water to the mixed solution, and mix evenly to form a suspension. Finally, 1g of sodium bicarbonate was added to the suspension, transferred to a closed reaction kettle, placed in an oven, and heated at 120°C for 20 hours. After the reaction, the resulting precipitate was filtered, washed with distilled water, and dried to obtain an anisotropic structure. CeO 2 Nanotube precursors. The precursor was heated at 450° C. for 5 hours under air flow to obtain a pale yellow sample. After washing and drying, pure CeO was obtained 2 nanotube.
[0037] The invention utilizes raw materials such as formate and carbonate which are cheap, and synthesizes cerium oxide nanotubes by means of a hydrothermal method. The cerium oxide nanotubes of the ...
