The invention discloses a preparation method for a copper aluminate spinel porous block. The preparation method comprises the following steps: first, dissolving a phase separation inducing agent in a solvent; then, adding copper chloride dihydrate, aluminium chloride hexahydrate and a complexing agent, and stirring until the copper chloride dihydrate, the aluminium chloride hexahydrate and the complexing agent are completely dissolved; next, adding a gelatinization accelerator dropwise and stirring uniformly to obtain a homogeneous solution; later on, sealing the homogeneous solution in a container, and gelatinizing for 1 to 5 minutes at 60 to 80 DEG C to obtain wet gel; finally, aging the wet gel for 6 to 12 hours at 60 to 80 DEG C, drying the aged wet, and performing heat treatment for 1 to 3 hours at 500 to 900 DEG C to obtain the copper aluminate spinel porous block.

The invention discloses a preparation method for nanometer aluminum nitride powder. The preparation method comprises the following steps: with aluminum chloride hexahydrate and dicyandiamide as raw materials, separately dissolving aluminum chloride hexahydrate and dicyandiamide in methanol; after heating and dissolving at a temperature of 30 to 80 DEG C, slowly adding a dicyandiamide solution into an aluminum chloride solution under stirring so as to obtain a clear transparent stable precursor salt solution; carrying out drying and adding obtained precursor salt powder into an alumina crucible; and carrying out calcining at 900 to 1000 DEG C under the protection of a nitrogen atmosphere and carrying out heat preservation for 2 to 5 h so as to obtain nanometer aluminum nitride powder. The preparation method is simple in process and low in production cost. The prepared aluminum nitride powder is small in particle size and high in purity, and has potential development and application value in fields like ceramic substrate material, heat-dissipation filling materials, ultraviolet optic devices, photoluminescent matrix materials and field emission devices.

A process for preparing aluminium polychloride from hydrochloric acid and aluminium hydroxide includes such steps as blowing appropriate quantity of chlorine gas into the mixed solution of hydrochloric acid and aluminium hydroxide, reaction of chlorine gas on water in the solution to generate hydrochloric acid and hypochlorous acid as catalyst for next reaction, and reaction of hydrochloric acid on aluminium hydroxide to generate aluminium hydroxychloride. Its advantages are simple process and equipment, short period, and high sterilizing, seaweed-killing and decolouring function. The product is an efficient water deaner.

The invention provides a method for grinding-assisted self-infiltration synthesis of highly efficient catalytic degradation of methylene blue metal mesoporous silica, comprising the following steps: S1. Dissolving the triblock copolymer P123 in water, adding aluminum chloride hexahydrate, and heating at 35°C Stir in a water bath for 0.5-1h; S2. Then add the silicon source, and continue to stir until precipitation occurs; S3. Put the mixed solution in S2 into a high-pressure reactor, and after 24 hours of hydrothermal aging at 100°C, filter to obtain a solid. Then wash and dry to obtain mesoporous silica containing a template; S4. Mix the mesoporous silica prepared in step S3 with anhydrous ferric trichloride, grind fully, then roast to remove the template to obtain metal Doped mesoporous silica material. The invention provides a method for synthesizing metal species-doped mesoporous silicon oxide with high-efficiency catalytic degradation of methylene blue, which is low in cost, simple in process, environmentally friendly, low-carbon, time-saving and energy-saving.
