V.C.5 Novel Non-Precious Metal Catalysts for PEMFC: Catalyst Selection through Molecular Modeling and Durability Studies
نویسنده
چکیده
Synthesize carbon-based metal-free catalysts and • carbon-composite catalysts for oxygen reduction reaction (ORR). Optimize catalytic active reaction sites as a function • of carbon support, surface oxygen groups, nitrogen content, surface modifiers, pyrolysis temperature, porosity, and the concentration of the non-metallic additive “X” in the catalyst matrix. Evaluate catalyst stability under various conditions • to demonstrate the potential of carbon-based catalysts to substitute conventional Pt catalysts currently used in the membrane electrode assembly (MEA).

متن کاملSynthesis of nitrogen-doped onion-like carbon and its use in carbon-based CoFe binary non-precious-metal catalysts for oxygen-reduction
Nitrogen-doped onion-like carbon-rich materials were synthesized by heat treatment of a ‘‘hybrid’’ containing hexamethylene diamine complex in the presence of Co and Fe species while preparing non-precious metal electrocatalyst for oxygen-reduction. As demonstrated by electrochemical rotating disk electrode and fuel cell tests, the binary CoFe-based catalyst containing graphitized onion-like ca...

Replacement of precious platinum with efficient and low-cost catalysts for electrocatalytic hydrogen evolution at low overpotentials holds tremendous promise for clean energy devices. Here we report a novel type of robust cobalt-nitrogen/carbon catalyst for the hydrogen evolution reaction (HER) that is prepared by the pyrolysis of cobalt-N4 macrocycles or cobalt/o-phenylenediamine composites an...
متن کاملIdentification of carbon-encapsulated iron nanoparticles as active species in non-precious metal oxygen reduction catalysts
The widespread use of fuel cells is currently limited by the lack of efficient and cost-effective catalysts for the oxygen reduction reaction. Iron-based non-precious metal catalysts exhibit promising activity and stability, as an alternative to state-of-the-art platinum catalysts. However, the identity of the active species in non-precious metal catalysts remains elusive, impeding the developm...
