[0047] Another object of the present invention is to provide a metal-doped modified layered δ-MnO 2 The preparation method comprises the following steps:
[0048] Step 1: feed;
[0049] Step 2: react under the set reaction conditions;
[0050] Step 3: post-processing the system obtained in step 2 to obtain the final product.
[0051] Metal-doped modified layered δ-MnO in the present invention 2 The preparation method is the hydrothermal method. Compared with other powder preparation methods such as sol-gel method and high-temperature solid-phase method, the powder prepared by hydrothermal method has complete grain development, small particle size, uniform distribution, light particle agglomeration, and cheaper raw materials can be used , easy to obtain suitable stoichiometry and crystal form.
[0052] Step 1, feed;
[0053] In step 1, the addition is adding a manganese-containing compound, wherein the manganese-containing compound is potassium manganate, potassium perman...
Embodiment 1
[0104] Add 70ml deionized water to the hydrothermal kettle, then add 1.58g KMnO 4 , 1.87g Al(NO 3 ) 3 ·H 2 O was added to the hydrothermal kettle, and stirred in deionized water for 30min, then 2ml of ammoniacal liquor of 0.15mol / L was added;
[0105] Then react the added raw materials in a hydrothermal kettle at 160°C for 12 hours, and the reaction ends;
[0106] Filter the solid-liquid mixture of the reaction liquid in the hydrothermal kettle, and wash the filter cake with deionized water until the pH value of the filtrate is 7 to obtain the filter cake; then dry the filter cake at 80°C for 12 hours to obtain the metal-doped modified layered δ-MnO 2 .
