Embodiment Construction

[0019] The present invention mainly comprises:

[0020] (1) Composite of carbon nanomaterials and chitosan.

[0021] Dissolve the nano-carbon material and chitosan in 1% acetic acid at a mass ratio of 1:10 to 10:1, and disperse ultrasonically for 10 minutes; add glutaraldehyde to cross-link and compound to obtain a nano-carbon material and chitosan composite material, and centrifuge Separation, washing, and vacuum drying at 40°C for 8 hours.

[0022] (2) Preparation of conductive polypyrrole-chitosan-nanocarbon material composite hydrogel.

[0023] The compound of pyrrole and nano-carbon-chitosan with a mass ratio of 20:1 to 5:1 is dissolved in a mixed solvent of water and ethanol, and the ultrasonic dispersion is uniform. Then add the same molar amount of FeNO as pyrrole 3 9H 2 O mixed, vigorously stirred at 0-4°C for 30s and then left to stand, then put into the current collector to form an initial gel. The gel was kept growing at 25-30°C for 5-30 days. The remaining s...

Abstract

The invention provides a method for manufacturing a shape-controllable double-function hydrogel anode material for a hybrid biological power source. According to the method, the hydrogel anode material is prepared by chitosan, carbon nanotube and polypyrrole, the hydrogel anode material can be taken as an anode material for the hybrid biological power source, so not only can biological electrons be generated, but also the biological electrons can be further stored, the hybrid biological power source has double functions of a microbiological fuel cell and a biological capacitor, the hydrogel three-dimensional material has open transparent large-hole structure through which mass transfer and attachment of microbes in the holes are facilitated, electrode biological compatibility is substantially improved through the chitosan, biomembranes are easy to hang, microbe attachment amount is enhanced, conductivity and electron storage capability are improved through CNT and polypyrrole, anode biological electrocatalytic activity and electron storage can be improved, and cell instantaneous output power is improved. The method is advantaged in that the process is simple, self-supporting can berealized to form multiple shapes, and the method has wide application prospects in actual applications.

Description

technical field [0001] The invention relates to a preparation method of a biological power source anode material, in particular to a preparation method of a three-dimensional porous hydrogel anode material with dual functions of generating and storing electrons. Background technique [0002] In recent years, the problems of energy shortage and environmental degradation have gradually intensified, and the research, development and utilization of waste biomass energy, especially the chemical energy of organic matter in wastewater, have attracted much attention. The microbial fuel cell is an electrochemical power generation device that uses microorganisms to degrade organic matter to generate electricity. MFC is of great help to the sustainability of water resource utilization, and at the same time provides a new idea for wastewater treatment. Wastewater generally requires continuous treatment, so microbial fuel cells will continue to generate electricity, but as fuel cells, th...
