ZIF-derived Fe,Co coordinated N/O-codoped three-dimensional tungsten–carbon matrix for the performance-enhanced zinc-air flow battery and water splitting

Fe-based dual-atom catalysts for the oxygen reduction reaction

“…Inspired by the current work on the synergistic catalysis of clusters, nanoparticles and atomic sites, the use of clusters and nanoparticles to enhance the activity and stability of diatomic catalysts has also become a possible strategy. 71,72 Li et al fabricated uniformly dispersed Fe and Co codoped with nitrogen/oxygen into a three-dimensional highly porous tungsten–carbon matrix in aqueous solvents by a simple method (Fig. 15a).…”

“…The enhanced electrocatalytic performance can be attributed to the synergistic effects of highly exposed Fe, Co–N/O x and Fe/Co nanoparticles of the active substance tungsten–carbon structure, optimized electronic structure, self-generated carbon nanotubes, and enriched hierarchical porous interfaces. 72…”

“…Similar to doping S, P and O in Fe-based SACs to achieve optimal modulation of the electronic structure, this strategy has also been researched and used for tailoring Fe-based DACs. 72,74,75 For instance, Zeng et al constructed highly active Fe 2 N 5 P sites on P-doped hollow carbon supports. Theoretical calculations suggest that the presence of P atoms on the Fe 2 N 5 P sites is favorable for the formation of OOH* and consequently enhances their activity.…”

Integrating single atoms with nanoparticle catalysts for efficient electrochemical energy conversion

“…6,7 Therefore, catalysts that can enhance the rates of electrochemical conversion are essential to the success of these electrochemical technologies. 8–11 At present, the most widely used catalysts are typically made of precious metals ( e.g. , platinum 12 and palladium 13 ) because of their exceptional catalytic activity.…”
