Transition-metal- and nitrogen-codoped carbide-derived carbon/carbon nanotube composites (M-N-CDC/CNT) have been prepared, characterized, used as cathode catalysts in anion-exchange membrane fuel cells (AEMFCs). As transition metals, cobalt, iron, a combination of both investigated. Metal nitrogen are doped through simple high-temperature pyrolysis technique with 1,10-phenanthroline the N precursor. The physicochemical characterization shows success metal doping well very similar...
A facile method for the preparation of precious metal-free catalysts oxygen reduction reaction (ORR) from lignin, dicyandiamide, and transition metal salts is presented. Magnesium acetate was employed as a precursor sacrificial template, enhancing porous structure catalysts. Iron content in catalyst materials optimized bimetallic containing Fe Co also prepared. The physicochemical analysis revealed uniform dispersion various nitrogen moieties centers on sheet-like carbon structures, along...
We study the physico-chemical properties and electrocatalytic activity towards oxygen reduction of two Fe–N–C catalysts based on carbide derived carbon.
Cobalt- and nitrogen-doped carbide-derived carbon/carbon nanotube (CDC/CNT) composites are prepared used as oxygen reduction reaction (ORR) electrocatalysts for an anion exchange membrane fuel cell (AEMFC) cathode. For the doping, high-temperature pyrolysis is applied using a cobalt salt nitrogen precursor (either dicyandiamide, urea, or melamine). During (i) new mesopores formed confirmed by N2 physisorption results, (ii) atomically dispersed present on catalysts detected scanning...
In this work, doped nanocarbon electrocatalysts for electrochemical oxygen reduction reaction (ORR) are prepared by high-temperature pyrolysis from Honeyol, cobalt and iron salts, dicyandiamide. MgO-based inorganic templates further used to increase the mesoporosity of catalyst materials. The templated bimetallic electrocatalyst containing (FeCoNC-MgOAc) showed excellent stability remarkable ORR performance in rotating disk electrode testing alkaline conditions. was tested anion-exchange...
Abstract Iron and nickel phthalocyanines along with different carbon supports, i. e., multi‐walled nanotubes (MWCNT), graphene, carbide‐derived carbon, Vulcan mesoporous (MC, from Pajarito Powder, LLC), are used to prepare six bimetallic (Fe, Ni) N‐doped carbon‐based catalysts. The aim of this work is investigate the electrocatalytic activity bimetal phthalocyanine‐modified nanocarbon catalysts, e. g., effect supports on oxygen reduction reaction (ORR) evolution (OER), including...
Realizing high-performance and long-life rechargeable zinc-air batteries (ZABs) requires developing highly efficient robust bifunctional electrocatalysts for oxygen reduction reaction (ORR) evolution (OER), as the low efficiency...
Abstract A simple synthesis method was used to prepare an active oxygen reduction reaction (ORR) electrocatalyst based on iron and nitrogen co‐doped graphene for polymer electrolyte fuel cell applications. For the of ORR catalysts, two different graphene‐based materials, commercially available (Gra) oxide (GO), were as carbon substrates. The half‐cell experiments conducted by using rotating disc electrode (RDE) revealed that Fe−N−Gra showed much higher electrocatalytic activity than Fe−N−GO...
