Influence of nitrogen doping on oxygen reduction electrocatalysis at carbon nanofiber electrodes

Article Abstract:

Mechanistic differences in the oxygen reduction reaction (ORR) reaction pathway between nondoped and N-doped carbon nanofiber (CNF) varieties are discussed. It was revealed that exposed edge plane defects and nitrogen doping are important factors for influencing adsorption of reactive intermediates and for enhancing electrocatalysis for the ORR at nanostructured carbon electrodes.

Opposite roles of O2 in No- and N2O-carbon reactions: An initio study

Article Abstract:

A detailed analysis and discussion of the reaction mechanism of N2 formation from NO- and N2O-carbon reaction in the presence of O2 is presented. The side-on approaches of chemisorption of either NO or O2 on carbon surface are more thermodynamically stable than the vertical pathways in the presence of excess O2.

Effects of site occupancy, cation relocation and pore geometry on adsorption kinetics in ETS-4

Article Abstract:

A study was conducted to explain the observed difference in gas diffusion in Na-ETS-4 and its strontium ion- exchanged variant Sr-ETS-4. Upon ion exchange, Sr-ETS-4 shows appreciable kinetic selectivity between methane and nitrogen, which can be further improved by controlled dehydration.
