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