We present a highly durable S-doped ORR catalyst fabricated via simple wet ball milling using expanded graphite. The expanded graphite was used to achieve a better exfoliation and an effective incorporation of S in the graphite nanoplatelets, which resulted in an improvement in ORR activity. GES exhibited less deactivation for long operating ...

In this study, ultra-thin and easily dispersible g-C 3 N 4 nanosheets were obtained by a simple wet ball-milling process. Morphological and structural analysis showed that increasing ball-milling speed resulted in a decrease in both particle size and the number of stacked layers in g-C 3 N 4 nanosheets, hence improving their dispersion stability. Thinner nanosheets obtained …
