Author:Mabena, LF; Modibedi, Remegia M; Ray, Suprakas S; Coville, NJDate:Jul 2012The oxygen reduction reaction (ORR) at the cathode of fuel cells plays an important role in controlling the performance of a fuel cell but the poor kinetics of the ORR hinders this performance. Currently platinum-based metals are the best ...Read more
Author:Matseke, Mphoma S; Luo, Hongze; Wen, L; Zheng, HaitoDate:Jun 2022NiFe2O4 is one of the most abundant and inexpensive spinels; however, its activity toward the oxygen reduction reaction (ORR) is relatively low. For the first time, Co-substituted Fe partly of the NiFe2O4 electrocatalyst was studied to improve ...Read more
