Abstract
The invention discloses a modified cobalt-manganese-oxide-doped carbon nanotube catalyst as well as a preparation method and application thereof. The preparation method comprises the following steps: (1), putting carbon nanotubes in a PDDA aqueous solution and carrying out ultrasonic dispersion, thereby obtaining a homogeneous solution; (2), firstly dispersing the obtained homogeneous solution in deionized water, adding a dimethylformamide solution and carrying out ultrasonic dispersion; then, dissolving Co2+ and Mn2+ in the mixed solution according to a molar ratio of 1 : (2-2.5), and slowly stirring till obtaining black precipitate; (3), washing the black precipitate by utilizing the deionized water, putting the washed precipitate in a polytetrafluoroethylene high-pressure reactor, heating for 8-10 hours at 160-180 DEG C, and finally drying the processed black precipitate, thereby obtaining the modified cobalt-manganese-oxide-doped carbon nanotube catalyst. The modified cobalt-manganese-oxide-doped carbon nanotube catalyst can successfully starts MFC and shortens a starting period of the MFC; compared with a comparison group Pt/C, the modified cobalt-manganese-oxide-doped carbon nanotube catalyst has better performance, and following the reduction of CoMn2O4 load, the performance of the MFC is also gradually improved.
