The invention discloses a three-dimensional flower-like
salicylic acid radical intercalation layered
hydroxide nano material and a preparation method thereof. The three-dimensional flower-like
salicylic acid radical intercalation layered
hydroxide nano material is nano
powder with uniform particles, the
diameter of the three-dimensional flower-like
salicylic acid radical intercalation layered
hydroxide nano material is 1-2mum, a
microstructure of the three-dimensional flower-like salicylic
acid radical intercalation layered hydroxide nano material is a flower-like structure, petals are nano slices grown uniformly, and thickness of each nano slice is 5-20nm. The preparation method of the three-dimensional flower-like salicylic
acid radical intercalation layered hydroxide nano material comprises the following steps of: mixing
mixed solution of soluble
divalent metal and soluble
aluminium salt with salicylate solution, and regulating pH value to be 6.5-7.5 with an alkaline solution; carrying out hydrothermal
crystallization for 12-72 hours at the temperature of 120-160 DEG C under standing condition; and washing and
drying, so that the three-dimensional flower-like salicylic
acid radical intercalation layered hydroxide nano material is obtained. A hydrothermal method is adopted for preparation, the obtained material has uniform nano particles, and the petals are slices grown uniformly. The preparation method disclosed by the invention has the characteristics of available raw materials, simple equipment and process, no guiding agent or modifier, high efficiency, high speed and high yield and is applicable to large-scale industrial production.
