Embodiment 1
[0035] The preparation of embodiment 1FeNi pyrolysis catalyst
[0036]1. Preparation of binary hydrotalcite:
[0037] 1) Weigh 0.1212g Fe(NO 3 ) 3 9H 2 O(0.3mmol) and 0.26172g Ni(NO 3 ) 2 ·6H 2 O (0.9mmol) was loaded into the tetrafluoroethylene lining, dissolved with 80mL deionized water, and then 0.2402g (4mmol) of urea was added;
[0038] 2) Add a magnet and stir for 1 hour at a speed of 900r / min;
[0039] 3) Take out the magnet, put the inner liner into the hydrothermal kettle, and react hydrothermally at 160°C under its own pressure for 20 hours;
[0040] 4) After the reaction is completed, the water bath is cooled, the reaction product is suction filtered, and then washed three times with absolute ethanol and deionized water (washed once with absolute ethanol, then once with deionized water, a total of three cycles), the washed The final product was placed in a vacuum drying oven, dried at 60°C for 12 hours, the dried product was ground, weighed, sampled, and sto...
