experiment example 1
[0031] Experimental Example 1: Nano Mesoporous Oxide NiO
[0032] Synthetic raw materials: sucrose, urea, Ni(NO 3 ) 2· 6H 2 O (nickel nitrate)
[0033] (1) Weigh 100 g sucrose, 1 g urea and 1 g Ni(NO 3 ) 2· 6H 2 O in a 100 mL beaker, then place the beaker in a heatable magnetic stirrer. The temperature of the magnetic stirrer was raised to 100°C, and the stirring was continued for 60 minutes until the drug in the beaker formed a uniform molten liquid.
[0034] (2) Put the beaker containing the molten liquid sample in (1) into an oven at 120°C, and react for 48 hours to obtain a dark brown puffy solid.
[0035] (3) Grind the product obtained in (2) with a mortar and put it in a crucible. The product obtained by the reaction is in N 2 Heat treatment at 1100°C for 2 hours under protection.
[0036] (4) Calcining the black solid described in (3) at 450°C in air for 24 hours to obtain nanometer mesoporous metal oxide NiO. The XRD test shows that the particle size of nano...

[0037] Experimental Example 2: Nano Mesoporous MgO-Al 2 o 3
[0038] Synthetic raw materials: glucose, urea, Mg(NO 3 ) 2· 6H 2 O (magnesium nitrate), Al(NO 3 ) 3· 9H 2 O (aluminum nitrate)
[0039] (1) Weigh 1 g glucose, 10 g urea, 0.1 g Mg(NO 3 ) 2· 6H 2 O and 0.1 g Al(NO 3 ) 3· 9H 2 O in a 100 mL beaker, then place the beaker in a heatable magnetic stirrer. The temperature of the magnetic stirrer was raised to 220°C, and the stirring was continued for 10 min until the medicine in the beaker formed a molten liquid.
[0040] (2) Put the beaker containing the molten liquid in (1) into an oven at 250°C and react for 1 hour to obtain a dark brown puffy solid.
[0041] (3) Grind the product obtained in (2) with a mortar and put it in a crucible. The product obtained by the reaction is in N 2 Heat treatment at 250°C for 40 hours under protection,
[0042] (4) Calcining the black solid described in (3) at 900°C in air for 7 hours to obtain nano-mesoporous MgO-Al 2...
experiment example 3
[0044] Experimental Example 3: Nano Mesoporous TiO 2
[0045] Synthetic raw materials: glucose, urea, TiOSO 4 (titanyl sulfate)
[0046] (1) Weigh 5 g of glucose and 1 g of urea into a 100 mL beaker, and then place the beaker in a heatable magnetic stirrer. The temperature of the magnetic stirrer was raised to 200°C, and the stirring was continued for 10 min until the drug in the beaker was in a molten state.
[0047] (2) Weigh 0.2 g TiOSO 4 And add it to the molten liquid mentioned in (1), and keep stirring for 10 minutes until the solution is clear. Then put the beaker into an oven at 200°C and react for 8 hours to obtain a dark brown puffy solid.
[0048] (3) Grind the product obtained in (2) with a mortar and put it in a crucible. The product obtained by the reaction was calcined at 700°C in the air for 7 hours to obtain nano-mesoporous TiO 2 . Figure 4 nanometer mesoporous TiO 2 The TEM picture, the nano-mesoporous TiO can be seen in the figure 2 It is rod-shap...
