Book synopsis

This work centers on development of Platinum free catalyst based on pyrolized vinazene carbon composite for oxygen reduction reaction in fuel cells and air battery cathodes. Oxygen (O2) is the most abundant element in the Earth's crust. But, the ORR kinetics, especially in the acidic medium, is very slow. To speed up the ORR kinetics to reach a practical level in fuel cell applications, an active and stable catalyst is needed. To date, platinum-based materials are the most practical catalysts used in fuel cells. However, Pt is scarce and costly. It is against this background that we are using novel vinazene based nitrogen precursor to develop highly active Fe-N-C catalysts for ORR using different carbon supports. The synthesized catalysts were characterized using electrochemical techniques (RDE, and stationary voltamperometry), BET and spectroscopic techniques (RAMAN, XRD,SEM-EDS, and XPS). The synthesized catalyst based on KB showed better activity than catalyst based on Vul. It also has good activity compared to Pt-based catalyst. However, both catalysts Fe-N-C/KB and Fe-N-C/Vulcan demonstrated very good stability and excellent methanol tolerance.
