Understanding its complex kinetics and developing advanced catalyst materials have the potential to drive significant improvements in energy efficiency, paving the way for sustainable, green energy solutions. In this work, Iron-Nitrogen-Carbon@aerogel (Fe(FcP)_x-N-C@Aerogel) catalysts are developed by carbonizing polypyrrole (PPy) and ferrocene. The ORR performance of these catalysts is investigated across different annealing temperatures. The catalysts’ shape and structure are validated through scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS), revealing that changes in annealing temperature affect morphology and nitrogen-containing functional groups of the catalyst. Linear sweep voltammetry (LSV) and rotating disk electrode (RDE) studies demonstrated that Fe(FcP)₈₀₀-N-C@Aerogel catalysts exhibit excellent performance, with a half-wave potential of 0.687 V and an average electron transfer number of 3.98 under acidic conditions. These findings suggest a near-four-electron reaction pathway, highlighting the catalyst's strong ORR activity, high efficiency, and durability, with only 17.4 mV LSV curve decay after 10,000 cycles.

Alloying these metals forms multicomponent catalysts with compelling properties. In this study, CoCrFeNi and MnCrFeNi thin films are synthesized using High-Power Impulse Magnetron Sputtering (HiPIMS) and their catalytic activity for the Oxygen Reduction Reaction (ORR), the Oxygen Evolution Reaction (OER), and corrosion resistance in 1 molar (1 M) potassium hydroxide (KOH) are evaluated. MnCrFeNi films exhibit a fine-grained single face-centered cubic (FCC) phase, while CoCrFeNi films have larger grains and multiple phases. ORR on CoCrFeNi follows a 2+1 electron transfer pathway, producing hydroxide radicals, while MnCrFeNi exhibits a 2-electron pathway, yielding hydrogen peroxide. Anodization reduces the CoCrFeNi overpotential from 0.9 to 0.5 V versus the reversible hydrogen electrode (RHE), comparable to platinum and iridium catalysts (Pt/C, Ir/C). Anodization also shifts CoCrFeNi ORR to a 2-electron pathway. In situ Raman spectroscopy detects no ORR intermediates, but nickel oxyhydroxide (NiOOH) appears during OER.

Rheological, compatibility, and thermal analyses are conducted on the sample blends. The MFI of the resulting blends ranges from 56 g/10 min (baseline PLA) to 238 g/10 min (PLA/PEG 400–10%), confirming their suitability for the melt-blowing process. These blends are then formed into nonwoven mats using a twin-screw extruder, producing microfibers with diameters between 1.05 and 2.64 µm. The second step involves boiling water etching to remove PEG, creating nanopores within the fibers. This etching process leaves a network of nanopores (50–200 nm in size), distributed throughout the microfiber structure.
