The invention discloses a method for preparing an air cathode of a microbial fuel cell by using petroleum cokes, relating to the preparation of electrodes of microbial fuel cells and particularly relating to a cheap and high-performance air cathode for a microbial fuel cell and a preparation method of the cheap and high-performance air cathode. A catalytic activation layer is prepared by using a petroleum coke activator in the method for preparing the air cathode of the microbial fuel cell by using petroleum cokes as raw materials. The method for preparing the air cathode comprises the following steps: petroleum coke activation; air diffusion layer preparation; catalytic activation layer preparation; air cathode drying. The method has the advantages that the manufacturing cost of the air cathode is further greatly reduced because the petroleum coke activator is used as the raw material of the catalytic activation layer; the petroleum cokes are recycled, and natural resources are sufficiently utilized; compared with the traditional activated carbon, the petroleum coke activator has larger specific surface area and higher catalytic activation, so that the electricity generation performance of the microbial fuel cell is improved.
