Tracing the trends in oxygen reduction [PDF]

Science, 2016
Electrochemistry Fuel cells currently rely too heavily on expensive platinum catalysts to reduce oxygen. Cheaper metals still have not matched the efficiency of platinum. Pegis et al. studied a series of well-defined iron porphyrin complexes in solution, in the interest of discerning which factors would be most productive to optimize.
