TL;DR: In this paper, a scalable metal organic framework-derived Fe-N-C catalyst with high ORR activity demonstrated in practical H2/air fuel cells, and an unprecedented turnover frequency (TOF) in acid in rotating disk electrode.

TL;DR: These results validate the use of independent DFT predicted BE shifts for defect identification and constraining ambient pressure XPS observations for Me-Nx moieties in pyrolyzed carbon based ORR electrocatalysts and supports the understanding of such catalysts as vacancy-and-substitution defects in a graphene-like matrix.

TL;DR: In this article, several different groups of iron-based catalysts were systematically studied by combining multiple spectroscopic techniques under ex situ and in situ conditions in an effort to obtain a comprehensive understanding of the synthesis-products correlations, nature of active sites, and the reaction mechanisms.

TL;DR: In this article, a non-platinum group metal (non-PGM) cathode catalysts were synthesized using a sacrificial support method (SSM) from iron-aminoantipyrine (Fe-AAPyr) derived materials.

TL;DR: In this paper, a series of Pd/ZnO catalysts with different Pd loadings were prepared using needlelike ZnO crystallites (N) with predominant (10−10) nonpolar facets exposed and commercial Zn O (P) without any dominant facets.
