preparation example Construction
[0030] The embodiment of the present invention provides a method for preparing a three-dimensional branched manganese dioxide nanomaterial, comprising:
[0031] S1: ultrasonically disperse amphiphilic organic molecules in water, adjust the pH value, and place at room temperature to obtain an organic template solution;
[0032] In this step, the self-assembly of amphiphilic organic molecules is first used to construct a one-dimensional organic template. Specifically, after the amphiphilic organic molecules are ultrasonically dispersed in water, the pH value of the system is adjusted to near neutrality, and the organic template solution is obtained by standing still for a period of time. In this step, the method of dispersing amphiphilic organic molecules in water to obtain a one-dimensional organic template is chosen so that the obtained one-dimensional organic template solution can be better mixed with the manganese-containing compound solution to form a uniform three-dimensi...
Embodiment 1
[0051] First, the amphiphilic organic molecules are ultrasonically dispersed in water, the pH value is adjusted to 3, and placed at room temperature to obtain an organic template solution; subsequently, potassium permanganate solution and manganese nitrate solution are added to the organic template solution, After stirring and mixing, react for 1-3 hours, and centrifuge to obtain a brown precipitate; finally, wash, dry and heat the brown precipitate, and obtain a three-dimensional branched manganese dioxide nanomaterial 1 after removing the organic template.
Embodiment 2
[0053] First, the amphiphilic organic molecules are ultrasonically dispersed in water, the pH value is adjusted to 6, and placed at room temperature to obtain an organic template solution; subsequently, potassium permanganate solution and manganese nitrate solution are added to the organic template solution, After stirring and mixing, react for 4-6 hours, and centrifuge to obtain a brown precipitate; finally, wash, dry and heat the brown precipitate, and obtain the three-dimensional branched manganese dioxide nanomaterial 2 after removing the organic template.

Description
technical field [0001] The invention relates to the technical field of supercapacitor electrode materials, in particular to a preparation method of a three-dimensional branched manganese dioxide nanometer material. Background technique [0002] The growth of the world's population and the rapid development of industry urgently need to provide more energy, which is currently mainly provided by the combustion of fossil resources such as oil, coal, and natural gas. On the one hand, the reserves of fossil resources are limited and difficult to regenerate; on the other hand, when these fossils are burned to provide energy, a large amount of toxic gases are released, which brings serious environmental pollution problems. Therefore, the development of clean and sustainable energy technology is an effective way to solve the contradiction between economic development and environmental protection. The emergence of supercapacitors provides a good opportunity for people to reduce the d...
