TL;DR: In this paper, a two-electrode configuration was proposed to produce nitrogen-doped porous carbon nanosheets using pine nut shells, an abundant biomass waste, as the precursor under the synergetic effect of KOH and melamine during the activation process.

TL;DR: NiCoP-CoP/NF affords a remarkable hydrogen evolution performance in terms of high activity, enhanced kinetics, and outstanding durability in an alkaline electrolyte, superior to most of the Co (or Ni)-phosphide-based catalysts reported previously.

TL;DR: In this article, the role of iron species in Fe-N-C nanohybrids for catalysing ORR by delicately tuning the iron chemical state was investigated, and it was shown that metallic iron species promote the electrocatalytic activity of Fe-Ns sites for ORR, while oxidative ones inhibit O2 adsorption on Fe-nx sites, decreasing their ORR activity.

TL;DR: The effect of N,P codoping on the conjugate carbon system and the synergistic effect between graphitic-N and P have been calculated through density functional theory calculations, which are essentially in agreement with experimental data.

TL;DR: The optimized ORR catalyst Co@NCNT-700 exhibit larger BET area, higher content of Co-N x and graphitic N, which performance could be improved in further through Cu doping, which would be potentially used to develop next generation energy conversion devices.
