Such a FeCo-Nx doped 3D network of carbon nanotubes effectively tolerates the volume strain and prevents the metal nanoparticles aggregation. In the interim, the 3D network of porous N-doped carbon nanotubes agrees fast electron transport to accomplish remarkably excellent rate capability. Consequently...
The abundance of exposed active sites, namely, the Co4N nanoparticles, single- atom Co, and heteroatomic N-doped carbon nanotubes, and multiple synergistic effects among these components provide suitable tailoring of the d-band center for facilitating vectorial electron transfer and efficient ...
Nitrogen-doped carbon coated transition metal hybrids for the removal of hazardous hexavalent chromium (Cr(VI)) has attracted increasing attention in wastewater treatment recently. In this study, three-dimensional nano-nickel particles embedded in N-doped carbon nanotubes supported on porous biochar (Ni...

field-effect transistors fromlarge band gap carbon nanotubes. These devices have a tunable threshold voltage in the technologically relevant range (−1.3 V≤ V th ≤ 0.5 V) and can carry up to 5-6 µA of current in the on-state. We achieve such performance by exposure to potassiu...
the precursor metal–organic complexes in this work were prepared under mild conditions and used without complex purification procedures. Compared with the pristine carbon nanotube, N-doped carbon nanotube with abundant mesopores contribute to the formation of nanoscale Co sites. This resultant electrocatal...
Recently, the ASC of the polypyrrole nanotubes (positive electrode)//N-doped carbon nanotubes (negative electrode) can pro- vide a wide working potential of 1.4 V, a specific energy of 28.95 Wh kg−1 with a specific power of 7.75 kW kg−1 and a cyclic stability of ca....
Herein, we develop an electrospinning technique followed by a high−temperature carbonization process to fabricate N−doped carbon fibers (NCF) with N−doped carbon nanotubes (NCNTs) vertically grown on the surface of NCF using the Fe species as catalysts. In the 3D hierarchical structures, ...
Carbon nanotube/carbon nanosheets can avoid stacking due to the existence of carbon nanotubes. However, Co3O4 nanomaterials are only supported on the surface of the composite material, and the mass transfer is good on carbon nanosheets but is poor between carbon nanosheets [16]. Therefore, it ...
