A manufacturing method of porous carbon composite material includes the following steps. First, a polymer template is provided, the polymer template includes a polymer compound, and the polymer template has a plurality of pores. A coating step is provided, wherein a metal compound is coated on the polymer template to form a transition intermediate. A heating step is provided, wherein the transition intermediate is heated for transforming the polymer template to a carbon template and transforming the metal compound to a coating layer, and the porous carbon composite material is obtained. Due to the coating layer directly coated on the polymer template, the morphology change of the polymer to carbon is confined. Therefore, the detail structure of the porous carbon composite material can be controlled more precisely, and the needs of more sophisticated applications can be met. |
