High cost of Pt-based electrocatalysts used for oxygen reduction reaction (ORR) is one of the obstacle to the commercialization of fuel cells. Base metal such as Co and Fe that is coordinated to nitrogen on carbon support (M-NC; M=Co or Fe) is promising as an alternative catalyst for Pt-based ORR catalyst.
In this study, the Fe-NC catalysts were prepared using pig blood waste as a catalyst precursor. Although the porphyrin contained in blood would be an ideal precursor for the Fe-NC catalyst, the pig blood includes many types of component, which can be a potential contaminant to the active site for ORR during the course of catalyst preparation. Therefore, an effective pretreatment of pig blood is required for the evolution of high performing active site. It revealed in this study that both removal of phospholipid and a hydrothermal treatment of resultant was essential for the generation of active site with high ORR activity. Compared to a commercial Pt/C, prepared Fe-NC showed high ORR activity, which is 1.3 times higher on a basis of kinetic current at 0.9 V (vs. RHE)
