Embodiment 1

[0029] Step A: the MgCl of 300mL 4mol / L 2 Aqueous solution (containing 114.3g MgCl 2 ) to 70°C, slowly add 4.8g of MgO powder under stirring condition (n MgO / n MgCl2 =0.1), stop heating after MgO is completely dissolved, let it stand at room temperature for 24 hours, then heat to 160°C for 4 hours, wash the obtained product, filter, and dry at 70°C for 6 hours, and the molecular formula is Mg 10 Oh 18 Cl 2 ·5H 2 O's fibrous basic magnesium chloride precursor.

[0030] Step B: Take 5g basic magnesium chloride precursor, disperse it in 250mL deionized water, adjust pH=13 with 1mol / L NaOH solution, and slowly add NaAlO dropwise under stirring condition 2 solution (2.88g NaAlO 2 dissolved in 150mL deionized water) and Na 2 CO 3 solution (3.73g NaCO 3 dissolved in 100mL deionized water) (Mg 2+ :AlO - :CO 3 2- =2:1:1), heated to 80°C for 7 h, washed, filtered, and dried at 70°C for 6 hours to obtain a fibrous MgAl-HTLs product with a Mg / Al atomic ratio of about 2.

Embodiment 2

[0032] Step A: Same as Step A of Example 1.

[0033] Step B: Take 5g basic magnesium chloride precursor, disperse it in 250mL deionized water, adjust pH=13 with 1mol / L NaOH solution, and slowly add NaAlO dropwise under stirring condition 2 solution (2.89g NaAlO 2 dissolved in 150mL deionized water) and Na 2 CO 3 solution (3.73g NaCO 3 dissolved in 100mL deionized water) (Mg 2+ :AlO - :CO 3 2- =2:1:1), heated to 95°C for 2 h, washed, filtered, and dried at 70°C for 6 hours to obtain a fibrous MgAl-HTLs product with a Mg / Al atomic ratio of about 2.

Embodiment 3

[0035] Step A: Same as Step A of Example 1.

[0036] Step B: Take 5g basic magnesium chloride precursor, disperse it in 250mL deionized water, adjust pH=13 with 1mol / L NaOH solution, and slowly add NaAlO dropwise under stirring condition 2 solution (1.93g NaAlO 2 dissolved in 150mL deionized water) and Na 2 CO 3 solution (2.49g NaCO 3 dissolved in 100mL deionized water) (Mg 2+ :AlO - :CO 3 2- =3:1:1), heated to 95°C for 2 h, washed, filtered, and dried at 70°C for 6 hours to obtain a fibrous MgAl-HTLs product with a Mg / Al atomic ratio of about 3.

Abstract

The invention relates to a one-dimensional morphology hydrotalcite like material and a preparation method of the same. The fibrous, whisker-shaped, rod-shaped and strip-shaped one-dimensional morphology hydrotalcite like material which is difficult to prepare by other methods can be prepared by solid-liquid ion exchange and synchronous crystal phase inversion processes. The dispersible uniformity of the material is improved and the bulk density is greatly reduced, so that the material is suitable to the fields of catalysis, adsorption, ion exchange and the like.

Description

Technical field: [0001] The invention relates to a hydrotalcite-like material with one-dimensional morphology and a preparation method thereof, belonging to the field of preparation of inorganic non-metallic functional materials. Background technique: [0002] Hydrotalcite-like compounds (HTLs for short) are composed of OH - Octahedrally coordinated divalent and trivalent metal ions (M II and M III ) array composed of positively charged brucite-like host laminates ([M II 1-x m III x (OH) 2 ] x+ ) and interlayer guest hydrated anions (A n- ) composed of a class of anionic layered materials, so it is also called anionic clay (anionic clays), its chemical composition can be expressed as the general formula: [M 2+ 1-x m 3+ x (OH) 2 ]A n- x / n mH 2 O, usually abbreviated as M II m III -A-HTLs. The tunability of host laminates and the exchangeability of guest anions between layers are the main features of hydrotalcite-like compounds. HTLs materials with the same...
