- Fe-N-C single-atom catalysts (SACs) have impressive peroxidase-like activity, mimicking natural enzymes due to isolated iron sites on a carbon substrate.
- Introducing phosphorus (P) heteroatoms into the carbon matrix of these SACs enhances their catalytic activity, with a specially designed 1D carbon nanowire catalyst showing better performance and stability.
- While a small amount of P significantly boosts POD-like activity, excessive P doesn't contribute further; this enhanced catalyst is successfully used for sensitive detection of acetylcholine.

Fe-N-C single-atomic metal site catalysts (SACs) are being explored as alternatives to platinum-based catalysts for oxygen reduction reactions in fuel cells.
Researchers aim to enhance the efficiency of these catalysts by modifying the electronic structure of their active sites, particularly through the use of heteroatom doping.
The study introduces chlorine as a near-range coordinator to improve the Fe-N active center, resulting in a catalyst (FeNCl SAC) that shows higher ORR activity compared to traditional FeN SAC, supported by theoretical calculations and experimental results.

- Jordan Alysia Barr's recent research focuses on enhancing the catalytic properties of iron single-atom catalysts (SACs) for applications in biosensing and fuel cells, specifically targeting their peroxidase-mimicking and oxygen-reduction activities.
- The introduction of heteroatoms, such as phosphorus, is explored to improve the catalytic efficiency of Fe-N-C SACs, aiming to achieve better performance in various applications while maintaining controlled interactions in their electronic structures.
- Barr's work signifies a pivotal shift towards developing cost-effective alternative catalysts in fuel cells, potentially reducing reliance on traditional platinum-based catalysts while optimizing the functionality of these single-atom systems.
