Embodiment 1
[0021] According to Example 3-1, a loose powder gel (ie, oxide precursor) was prepared. Afterwards, the oxide precursor was roasted at 800° C. for 3 hours under normal pressure with nitrogen protection at a flow rate of (30-50 ml / min) to obtain a black carbon-containing oxide intermediate. Finally, the black carbon-containing oxide intermediate was calcined at 400°C in the air for 3 hours to obtain ultrafine zirconium cerium oxide. Characterized by XRD, TEM and BET, the prepared cerium zirconium oxide was ultrafine Nanomaterials, see Attached Table 1 and Attached figure 1 , attached figure 2 , attached Figure 4 .
Embodiment 2
[0025] Weigh 32.37g Ce(NO 3 ) 3 ·6H 2 O, 8.00g Zr(NO 3 ) 4 ·5H 2 O and 16.16g of malic acid were mixed and dissolved in an appropriate amount of deionized water to obtain a precursor solution. Then, under the condition of stirring, heat with electric furnace with controlled current, carefully evaporate to a viscous sol, and dry it at about 100°C for 10-14 hours to obtain a loose powder gel (that is, the oxide precursor). Afterwards, the oxide precursor was roasted at 600° C. for 3 hours under normal pressure with nitrogen protection at a flow rate of (30-50 ml / min) to obtain a black carbon-containing oxide intermediate. Finally, the black carbon-containing oxide intermediate was calcined at 400°C in the air for 3 hours to obtain ultrafine cerium-zirconium oxides. Characterized by XRD, TEM and BET, the prepared cerium-zirconium oxides were ultrafine cerium-zirconium oxides with high specific surface area. Nanomaterials, see Attached Table 1 and Attached Figure 1~3 .
Embodiment 3
[0029] Weigh 7.30g Ce(NO 3 ) 2 ·6H 2 O, 28.87g Zr(NO 3 ) 2 ·6H 2 O and 17.66g of citric acid were mixed and dissolved in an appropriate amount of deionized water to obtain a precursor solution. Then heat it with a water bath under the condition of stirring, carefully evaporate to a viscous sol, and dry it at about 100°C for 10 to 14 hours to obtain a loose powder gel (that is, the oxide precursor). Afterwards, the oxide precursor was roasted at 600° C. for 3 hours under normal pressure with nitrogen protection at a flow rate of (30-50 ml / min) to obtain a black carbon-containing oxide intermediate. Finally, the black carbon-containing oxide intermediate was calcined at 400°C in the air for 3 hours to obtain ultrafine zirconium cerium oxide. Characterized by XRD, TEM and BET, the prepared zirconium cerium oxide was ultrafine For nanomaterials, see Attached Table 1.
