Single walled carbon nanotube in the reaction layer of gas diffusion electrode for oxygen reduction reaction
In this paper, the effect of surface area of reaction layers in gas diffusion electrodes on oxygen reduction reaction was investigated. For this purpose, various amounts (0.1, 0.2, 0.3, 0.4, 0.5, 1, 1.5 and zero %wt of total loading of reaction layer) of single walled carbon nanotube (SWCNT) were inserted in the reaction layer. The performance of gas diffusion electrodes for oxygen reduction re...
متن کاملDurability of Pt/graphitized carbon catalysts for the oxygen reduction reaction prepared by the nanocapsule method.
Monodisperse Pt nanoparticles supported on a graphitized carbon black (GC; 150 m(2) g(-1)), which exhibits higher resistance to carbon corrosion than a conventional high-surface-area carbon black (CB; 800 m(2) g(-1)), were prepared by the nanocapsule method. Three kinds of 50 wt%-Pt loaded catalysts (our nanocapsule Pt/GC, a commercial Pt/GC, and a commercial Pt/CB) were subjected to the durabi...
متن کاملIn situ Fe2N@N-doped porous carbon hybrids as superior catalysts for oxygen reduction reaction.
Developing efficient and economical noble-metal free catalysts for oxygen reduction reaction (ORR) is one of the essential factors for the industrialization of fuel cells. Recent studies on transition metal ORR catalysts have become the priority to practical low-temperature fuel cells. Herein, we proposed a novel in situ design, Fe2N nanoparticles (NPs) in an N doped porous carbon matrix (Fe2N@...
متن کاملNanostructured nonprecious metal catalysts for oxygen reduction reaction.
Platinum-based catalysts represent a state of the art in the electrocatalysis of oxygen reduction reaction (ORR) from the point of view of their activity and durability in harnessing the chemical energy via direct electrochemical conversion. However, because platinum is both expensive and scarce, its widespread implementation in such clean energy applications is limited. Recent breakthroughs in...
متن کاملBiomass-derived nitrogen self-doped porous carbon as effective metal-free catalysts for oxygen reduction reaction.
Biomass-derived nitrogen self-doped porous carbon was synthesized by a facile procedure based on simple pyrolysis of water hyacinth (eichhornia crassipes) at controlled temperatures (600-800 °C) with ZnCl2 as an activation reagent. The obtained porous carbon exhibited a BET surface area up to 950.6 m(2) g(-1), and various forms of nitrogen (pyridinic, pyrrolic and graphitic) were found to be in...
