Highly efficient noble-metal-free electrocatalysts for oxygen reduction reaction (ORR) are essential to reduce the costs of fuel cells and metal–air batteries. Herein, a single-atom Ce–N–C catalyst, constructed atomically dispersed Ce anchored on N-doped porous carbon nanowires, is proposed boost ORR. This catalyst has high content 8.55 wt % activity with ORR half-wave potentials 0.88 V in alkaline media 0.75 acidic electrolytes, which comparable widely studied Fe–N–C catalysts. A Zn–air...
Abstract Multifunctional nanozymes can benefit biochemical analysis via expanding sensing modes and enhancing analytical performance, but designing multifunctional to realize the desired of targets is challenging. In this work, single‐atomic iron doped carbon dots (SA Fe‐CDs) are designed synthesized a facile in situ pyrolysis process. The small‐sized CDs not only maintain their tunable fluorescence, also serve as support for loading dispersed active sites. Monoatomic Fe offers SA Fe‐CDs...
Abstract Fe–N–C single‐atom catalysts (SACs) exhibit excellent peroxidase (POD)‐like catalytic activity, owing to their well‐defined isolated iron active sites on the carbon substrate, which effectively mimic structure of natural peroxidase's center. To further meet requirements diverse biosensing applications, SAC POD‐like activity still needs be continuously enhanced. Herein, a phosphorus (P) heteroatom is introduced boost SACs. A 1D nanowire (FeNCP/NW) catalyst with enriched Fe–N 4...

Fe-N-C single-atomic metal site catalysts (SACs) have garnered tremendous interest in the oxygen reduction reaction (ORR) to substitute Pt-based proton exchange membrane fuel cells. Nowadays, efforts been devoted modulating electronic structure of sites for enhancing catalytic activities SACs, like doping heteroatoms modulate Fe-Nx active center. However, most strategies use uncontrolled long-range interactions with on substrate, and thus effect may not precisely control near-range...

Abstract Carbon‐based single‐atom catalysts (CSACs) have recently received extensive attention in catalysis research. However, the preparation process of CSACs involves a high‐temperature treatment, during which metal atoms are mobile and aggregated into nanoparticles, detrimental to catalytic performance.
