Self-standing Fe-N-C cathodes prepared by …

The aim of this PhD thesis project was the development of self-standing Fe-N-C cathodes prepared by electrospinning, in order to achieve hierarchical microporous and macroporous electrodes. Such a structure is desirable to improve accessibility by O2 of the Fe-based active sites for oxygen reduction reaction (ORR), and therefore to improve the performance of Fe-N-C cathodes in proton exchange ...

Ball-milling in liquid media: Applications to the ...

2005-1-1 · A grinding for 48 h (with the 10 mm balls) leads to a less defined (1 0 l) peak and it is quite difficult to distinguish hexagonal and rhombohedral phases. This is the sign of some disorders, although the compound remains quite well crystallized as shown by a low background, the sharpness of the reflections and the interplanar distance (3.35 Å).
