[0024] According to the mass ratio of 20:30:50:1, mix bauxite, montmorillonite, citric acid solution with a concentration of 0.5mol / L and nickel boride, put them into a high-pressure reactor, heat up to 150°C, and Stir and react for 1 hour; after the reaction is finished, filter and separate to obtain the reaction filter residue, mix the reaction filter residue and sodium hydroxide at a mass ratio of 10:1, move it into a tubular resistance furnace, and heat up to 400°C, keep warm for 1 hour; after the reaction is over, take out the reaction product, wash the reaction product repeatedly with deionized water until the washing solution is neutral, and dry it naturally to obtain a self-made functional material. The sodium silicate solution is mixed according to the mass ratio of 1:5 to obtain a mixed solution; the mixed solution is stirred with a magnetic stirrer at a speed of 200r / min, and the pH of the above mixed solution is adjusted to 1mol / L hydrochloric acid with a concentrat...
