“…S1A, ESI†) and Fe III/II is reported to be the active redox couple for the ORR. 12–15 In our pursuit, we found that the Fe III/II couple is responsible for O 2 reduction in non-aqueous medium (DMF : H 2 O : 1 : 1) as well. Also, Fe III/II is the active species for hydrazine oxidation in the DMF : H 2 O mixture following 1st-order kinetics with respect to hydrazine (Fig.…”

“…As shown in the literature, graphitization is very favorable for the enhanced electronic conductivity of a material. 45 The presence of C-N bonds confirms successful doping. The strong electron-accepting ability of N facilitates the formation of positively charged C atoms, which, in turn, enhances O 2 adsorption and accelerates the ORR.…”

The oxygen reduction reaction (ORR) is a crucial cathodic process and a technology providing renewable energy. It is essential to create ORR catalysts not containing noble metals yet still affordable and possessing high-efficiency and long-term durability. Therefore, this work developed a highly porous N-doped carbon catalyst embedded with CeO2 nanoparticles (NPs). This composite catalyst was synthesized by pyrolysis of PANI-encapsulated CeO2 NPs (CeO2/PANI) combined with in situ polymerization. The resulting catalyst exhibited an outstanding ORR performance with 0.94 and 0.81 mV onset and positive half-wave potentials, respectively, and 5.52 mA cm−2 diffusion-limited current density. The catalyst also demonstrated excellent stability. These exceptional characteristics indicate that a synergy of the N-doped carbon and CeO2 NPs provide a novel strategy of fabrication of novel ORR catalysts without using noble-metals for applications related to fuel cells and metal-air batteries.

“…The nitrogen source addition of Fe/N -CPC catalyst promotes the formation of FeS compare to Fe-CPC catalyst. FeS has no positive effect on oxygen reduction reaction [12,22]. Carbon peaks only appear in Fe-CPC catalyst indicating no metal interaction on a carbon support structure, therefore no catalyst functional can be formed after pyrolysis.…”

This paper investigates the physical properties and electrochemical properties of the innovative non-precious metal catalyst using different carbon types. The cathode catalyst for PEMFC (Proton Exchange Membrane Fuel Cell) is an important part of fuel cell because the reaction of the cathode is three times lower than the anode. Otherwise, the high cost of Pt/C catalyst for cathode needs to be replaced using low-cost material. Therefore, this research fabricated Pt free catalyst. FeCl3.6H2O was used as a metal precursor. Urea and PVP as a nitrogen (N) source were mixed with carbon. The variations of carbon are Graphite (Gt), Charcoal Active (CA), and Calcined Petroleum Coke (CPC). As prepared catalysts, were noted as Fe/N-Gt, Fe/N-CA, and Fe/N-CPC. Catalysts without nitrogen addition also were synthesized such as Fe-Gt, Fe-CA, and Fe-CPC for comparison. The electrochemical properties can be evaluated form Cycle Voltammograms (CV) curve. Graphite supported catalyst has anodic and cathodic peak otherwise has the lowest capacity. It means that the redox reaction occurs during CV measurement for Fe/N-Gt and Fe-Gt catalyst. Nitrogen addition of graphite supported catalyst has a higher current density than Fe-Gt catalyst. The morphology of the catalyst was identified by Scanning Electron Microscope (SEM). Different particle shape for carbon types can be observed by SEM image of obtained catalyst. Energy Dispersive X-Ray EDX to identify the chemical composition. Nitrogen-doped carbon caused the formation of Fe2O3 and it was determined by X-ray diffraction (XRD).
