Platinum group metal-free (PGM-free) catalysts based on MNC types of materials with M as
Mn, Fe, Co and Ni and aminoantipyrine (AAPyr) as NC precursors were synthesized using …

A series of tri-metallic oxygen reduction catalysts derived from pyrolyzed Fe-M 1-M 2 (where
M= Co, Ni, Cu and Mn) and 4-aminoantipyrine (Fe-M 1-M 2-AAPyr) were prepared using a …

A new synthesis route aimed at the preparation of electrocatalysts to be used for fuel cells is
described. A precursor material is prepared starting from a platinum chloride and a nickel …

The development of non-noble metal catalysts is of great interest due to their significant
potential application in both fuel cell systems and metal–air batteries, particularly when …

The effect of the metal for the oxygen reduction reaction (ORR) in acid medium with non-
precious metal catalysts has been investigated. A series of non-precious metal catalysts with …

Carbon-supported non-noble metal catalysts with Fe as the metal and tripyridyl triazine
(TPTZ) as the ligand (Fe-TPTZ/C) were synthesized using a simple chemical method. How …

This study examines the role of transition metals (Co or Fe) on nitrogen-modified carbon-
based catalysts for the oxygen reduction reaction (ORR). The nitrogen-modified carbon …

In recent years, non-precious metal electrocatalysts for oxygen reduction reaction (ORR)
have attracted tremendous attention due to their high catalytic activity, long-term stability and …

The activity and stability of non-precious metal catalysts (NPMCs) for the oxygen reduction
reaction (ORR) in both acid and alkaline electrolytes were studied by the rotating disk …

Metal-free nitrogen modified carbon catalysts (NC) are very closely related to MNC catalysts
which contain a transition metal (s)(M), usually Fe or Co as an essential constituent. We …
