Nano-structured ternary niobium titanium nitrides as durable non-carbon supports for oxygen reduction reaction.
A novel, highly stable, non-carbon support system for the oxygen reduction reaction (ORR) has been discovered in the form of nano-structured (NbxTi1-x)Ns (x = 0.25 and 0.5). Template-free, solid-solid separation synthetic approaches have been used for preparing these materials. The (NbxTi1-x)N materials have high specific surface area and better electronic conductivity than carbon-based supports.

Development of Ruthenium-Based Catalysts for Oxygen Reduction Reaction
A process was developed to synthesize ruthenium-based chelate RuNx electrocatalysts for the oxygen reduction reaction, using RuCl3 and propylene diammine as the Ru and N precursors, respectively. High-temperature pyrolysis has a critical role in the formation of the catalytic Ru–N sites for oxygen reduction. The RuNx catalyst modified in the presence of nitrogen-containing organic exhibited com...
متن کاملSingle 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...
