Zn‐Based Oxides Anchored to Nitrogen‐Doped …

Zn−Co oxide (ZnCoO x), Zn−Mn oxide (ZnMnO x), Zn−Mn−Co oxide (ZMCO), and Zn−Co−Fe oxide (ZCFO) nanoparticles were successfully synthesized on nitrogen‐doped carbon nanotubes in a one‐pot process.Porous carbon paper was simultaneously impregnated with the catalysts during synthesis and used as air electrodes for Zn‐air batteries.

Metal-free catalysis based on nitrogen-doped carbon ...

The results indicate that the catalytic activity for the ORR of nitrogen-doped CNTs with an onset potential at about 0.5 V is much higher positive than that of pristine CNT, although the onset potential is still 0.1 V lower than that of the Pt–C catalyst.

In situ nitrogen-doped, defect-induced carbon …

2020-3-23 · The present work focuses on nitrogen-doped, defect-induced surface-modified carbon nanotubes (MN-BCNT) having the synergy of both the effects to improve the electrochemical performance of the NIB. Initially, in situ nitrogen-doped CNTs were grown using a scalable, cost-effective and green synthesis technique.

Facile Synthesis of ZnO Nanoparticles on Nitrogen …

The improved electrochemical properties of the composite with the nitrogen doped CNT compared with the pristine CNT counterpart could be ascribed to the effect of topological defects on the NCNT : Firstly, the higher concentration of nucleation sites in NCNT favors formation of the smaller size non-agglomerated ZnO particles with more uniform ...

A Free-Standing Sulfur/Nitrogen-Doped Carbon …

A free-standing sulfur/nitrogen-doped carbon nanotube (S/N-CNT) composite prepared via a simple solution method was first studied as a cathode material for lithium/sulfur batteries. By taking advantage of the self-weaving behavior of N-CNT, binders and current collectors are rendered unnecessary in the cathode, thereby simplifying its manufacturing and increasing the sulfur weight ratio in the ...
