KOH activated Carbon Multiwall Nanotubes [PDF]

open access: yesCarbon: Science and Technology, 2009
A protocol for chemical activation of Multi-walled carbon nanotubes (MWNTs) is presented. The modification of multi-walled carbon nanotubes is obtained by the solid / solid reaction between KOH andcarbon nanotubes in a steinless cell under vacuum.

f‐p‐d Gradient Orbital Coupling Induced Spin State Enhancement of Atomic Fe Sites for Efficient and Stable Oxygen Reduction Reaction

open access: yesAdvanced Functional Materials, EarlyView.
The f‐p‐d (Eu─O─Fe) gradient orbital coupling induces electron delocalization and the introduced f‐band of Eu shifts the spin state of the Fe center in FePc from low‐spin to intermediate‐spin. This strategy simultaneously enhances oxygen reduction reaction (ORR) activity, reaction kinetics, and stability, resulting in superior ORR performance and ...

Nondispersive and dispersive collective electronic modes in carbon nanotubes

open access: yes, 2004
We propose a new theoretical interpretation of the electron energy-loss spectroscopy results of Pichler {\it et al.} on bulk carbon nanotube samples. The experimentally found nondispersive modes have been attributed by Pichler {\it et al.} to interband ...
