Design and structural engineering of single-atomic-site catalysts for acidic oxygen reduction reaction

Atomically dispersed Fe/Co dual site electrocatalysts derived from covalent triazine frameworks for boosting oxygen reduction

“…Therefore, increasing the density of active sites and selecting appropriate carbon precursors are effective methods to improve the overall activity and stability. [15][16][17][18][19][20] Covalent triazine frameworks (CTFs) are nitrogen-containing aromatic polymer frameworks with triazine rings, which have attracted extensive attention in the elds of catalysis, energy storage and conversion due to their unique porous structure, mechanical stability and high design exibility. The most common synthesis method of CTF-derived catalysts is ionothermal polymerization of aromatic hydrocarbon monomers.…”

A simple decagram-scale synthesis of an atomically dispersed, hierarchically porous Fe–N–C catalyst for acidic ORR

“…Fe-N 4 ) on a conductive carbon matrix, such materials exhibit outstanding ORR activity and selectivity in acid and alkaline media in comparison to other PGM-free catalysts. [18][19][20][21][22][23][24][25][26] To translate the promise of SACs into practical fuel cell cathodes, highly active catalytic sites are not enough. 27 First, to achieve high power density, the reactants and products must move fast through the material.…”

PEGylated Ni Single-Atom Catalysts as Ultrasensitive Electrochemiluminescent Probes with Favorable Aqueous Dispersibility for Assaying Drug-Resistant Pathogens

“…Typically, SACs are prepared by calcining metal precursors on the carriers to promote the formation and improve stability of atomically dispersed metal active centers. − However, high-temperature calcination inevitably destroys the hydrophilic groups of SACs and lowers their aqueous dispersibility. Thus, it is a huge challenge to apply SACs as signal probes to tag biorecognition molecules for bioassay although they have displayed high catalytic activity superior to natural enzymes and regular nanomaterials.…”
