Problems solved by technology

Although post-processing can control the doping amount and morphology of materials, it inevitably uses expensive or toxic precursor materials, making them unsuitable for practical applications
Therefore, it is still challenging to find an inexpensive, scalable, and environmentally friendly preparation method for heteroatom-doped carbon materials.

Abstract

The invention discloses a microbial enrichment preparation method of a hypha-based doped supercapacitor material, which comprises the following steps: preparing a liquid culture medium, inoculating afungus strain into the liquid culture medium, and carrying out shake culture; adding a polysaccharide-iron complex and a carboxymethyl chitosan-iron complex into a liquid culture medium in the form ofa solution or a dispersion liquid, continuously culturing, pouring out the redundant liquid culture medium, cleaning with deionized water, carrying out freeze drying, calcining the dried sample in anN2 atmosphere, and naturally cooling; adding the pyrolysis product into an H2SO4 solution, stirring and refluxing, then centrifugally collecting, washing with deionized water to be neutral, carryingout vacuum drying, and calcining the material subjected to vacuum drying again in an NH3 atmosphere; and obtaining the hypha-based doped supercapacitor material. The hypha-based doped supercapacitor material disclosed by the invention is high in specific surface area and high in iron doping amount,and the material has good capacitance performance and can be widely applied to the fields of energy storage, catalysis, environmental protection and the like.

Description

technical field [0001] The invention belongs to the field of preparation of supercapacitor materials, and relates to a method for preparing microbial enrichment of supercapacitor materials doped with mycelium bases. Background technique [0002] Fuel cells, metal-air batteries, dye-sensitized solar cells, lithium-ion batteries, and supercapacitors, as high-performance, low-cost, and environmentally friendly electrochemical energy storage conversion systems, are new energy devices that can replace traditional fossil fuels. And heteroatom (such as N, S, P, Fe, Co, and Ni) doped carbon materials show great potential in the construction of these devices due to their unique electronic properties as well as surface morphologies. Heteroatom-doped carbon materials are used as electrode materials for supercapacitors. Due to the synergistic effect of double-layer capacitors and pseudocapacitors, heteroatom-doped carbon materials have excellent capacitive properties. [0003] In recen...
