Synthetic method of layered flower type shell powder based nickel aluminum hydrotalcite

The invention relates to a synthetic method of layered flower type shell powder based nickel aluminum hydrotalcite. The method comprises the following steps of: stirring and dissolving nickel nitrate and aluminum nitrate at molar ratio of 2:1 in distilled water, performing ultrasonic dispersion for 10-15 minutes to prepare a liquid A; dissolving urea and shell powder in deionized water, performing ultrasonic dispersion for 10-15 minutes to prepare a liquid B; adding the liquids A and B into a reactor, performing microwave treatment under protection of nitrogen, wherein the reaction temperature is 90-120 DEG C, the treatment time is 1-2.5 hours, and the treatment power is 300-500W; after reaction, naturally cooling to room temperature, filtering, washing until the obtained product is neutral by deionized water, and placing in an oven for drying for 10-12 hours at 70-80 DEG C, and grinding to obtain the flower type shell powder based nickel aluminum hydrotalcite. The method provided by the invention is simple t
