Single-atom Fe-N-C catalysts are considered a candidate to replace the platinum group metals in oxygen reduction reaction (ORR), due to its high activity, anti-toxicity, and metal atom utilization1,2,3,4. Advanced Fe-N-C materials show comparable ORR performance to that of benchmark Pt/C3...
spectra of Cu K-edge in 2D-Cu–N–C, 2D-FeCu–N–C, and FePc@2D-Cu–N–C display a main peak at ~1.5 Å (not corrected for phase shift) due to the Cu–N coordination (Fig.3c). All wavelet transform (WT) contour plots at the Fe/Cu K-edge of 2D-FeCu–N–C, and F...

Density functional theory calculation results revealed that a CNT played a key role in optimizing the distribution of bonding and antibonding states in the Fe 3d orbital, resulting in the outstanding ability of FeSA-N-CNT for PMS chemical adsorption and activation. Moreover, CNT could significantly...
Firstly, the adsorption geometries and magnetic properties of different gas reactants on 555-777-graphene-Fe substrate are discussed in detail. It is found that the coadsorption of O2/NO or O2/CO molecules are more stable than that of the single NO or CO, indicating that the presence of ...
Single-atom Fe-Nx sites were confirmed to be the main active sites for PMS activation. FeSA-N/C-20 with a higher density of Fe-Nx sites exhibited superior catalytic performance to N/C, FeSA-N-C, FeSA-N/C-15, and FeSA-N/C-25 for BPA degradation. Integrated with chemical quenching ...
Steam explosions of a metallic melt as its degree of oxidation increases: Fe, FeO/sub 1/ /sub 0/, and FeO/sub 1/ /sub 2/. [PWR; BWR] Laboratory-scale steam explosions have been initiated reproducibly by exploding a submerged bridgewire shortly after single drops of melt are released int...
In overall water splitting and rechargeable Zn-air battery devices containing the Fe-N4SAs/NPC catalyst, it exhibits high efficiency and extraordinary stability. This current PPE method is a general strategy for preparing M SAs/NPC (M=Co, Ni, Mn), bringing new perspectives for designing various...
摘要: A Fe-N-C single-atom nanozyme-linked immunosorbent assay was developed.Aflatoxin B1(AFB1) could be detected within 50min.The results are reliable and sensitive.The method was successfully applied to quantification of AFB1in peanut samples....
