Embodiment 1
[0024] 1. Weigh Cu(NO 3 ) 2 ·3H 2 O4g, Mg(NO 3 ) 2 ·6H 2 O12.8g, Fe(NO 3 ) 3 9H 2 O13.4g was dissolved in 100ml deionized water by stirring to make it completely dissolved; respectively weighed NaOH6.4g, NaOH 2 CO 3 7.1g in 100ml deionized water, stir to dissolve completely;
[0025] 2. Add the two solutions obtained in step 1 into the rotating liquid film reactor at a certain flow rate to nucleate rapidly, and circulate for 2 minutes, then place the mixed solution in a hydrothermal kettle, and crystallize at a temperature of 100°C for 48 hours. Then wash the filtrate with deionized water to make the pH value of the washing water less than 8, and then dry at 60° C. for 24 hours to obtain the copper-magnesium-iron hydrotalcite precursor.
[0026] 3. Put the copper-magnesium-iron hydrotalcite precursor prepared in step 2 in a muffle furnace, raise the temperature to 500°C at 2°C / min, keep it warm for 6h, and cool down to room temperature naturally; then perform reducti...

[0030] 1. Weigh Cu(NO 3 ) 2 ·3H 2 O9.1g, Mg(NO 3 ) 2 ·6H 2 O9.6g, Fe(NO 3 ) 3 9H 2 O10.1g in 100ml deionized water, stirred to make it completely dissolved; Weigh respectively NaOH6.4g, NaOH 2 CO 3 5.3g in 100ml deionized water, stir to dissolve completely;
[0031] 2. Add the two solutions obtained in step 1 into the rotating liquid film reactor at a certain flow rate to quickly nucleate, and circulate for 2 minutes, then place the mixed solution in a hydrothermal kettle, and crystallize at a temperature of 100°C for 48 hours. Then wash the filtrate with deionized water to make the pH value of the washing water less than 8, and then dry at 60° C. for 24 hours to obtain the copper-magnesium-iron hydrotalcite precursor.
[0032] 3. Place the copper-magnesium-iron hydrotalcite precursor prepared in step 2 in a muffle furnace, raise the temperature to 500°C at 2°C / min, keep it warm for 6h, and cool down to room temperature naturally; then perform reduction treatment, th...
