Preparation method and application of reed biochar-based composite electrode material
The invention discloses a preparation method and an application of a reed biochar-based composite electrode material, and belongs to the technical field of electrode material preparation. The method comprises the following steps: selecting reed as a biochar raw material, and grinding defoliated, cleaned and dried reed to obtain a reed powder; putting the ground reed powder into a tubular furnace,and carrying out pyrolysis at a certain heating rate for a certain heating time to obtain a biochar powder; and mixing the biochar powder with polyaniline and a polyethylene binder according to a massratio of 5:1:4, placing the obtained mixture in the tubular furnace, and carrying out pyrolysis at a certain heating rate for a certain heating time to finally obtain the biochar-based composite electrode material. The reed biochar-based composite electrode material prepared in the invention has good conductivity, water resistance and biocompatibility, and can be used as a cathode of a bottom mudmicrobial fuel cell.
本发明公开了一种芦苇生物炭基复合电极材料的制备方法和应用，属于电极材料制备技术领域。本发明所述的方法选用芦苇作为生物炭原料，将去叶洗净干燥后的芦苇进行研磨得到芦苇粉末；研磨后的芦苇粉末置于管式炉中以一定的升温速率和加热时间进行热解得到生物炭粉末；再将生物炭粉末与聚苯胺和聚乙烯粘结剂分别按照5:1:4的质量比混合并置于管式炉中以一定的升温速率和加热时间进行热解，最终得到生物炭基复合电极材料。本发明制备得到的芦苇生物炭基复合电极材料具有良好导电性、耐水性和生物相容性，能够作为底泥微生物燃料电池的阴极。
