Water Confined in Hydrophobic Cup-Stacked Carbon Nanotubes beyond Surface-Tension Dominance

The Journal of Physical Chemistry Letters, 2019
Water confined in carbon nanotubes (CNTs) can exhibit distinctly different behaviors from the bulk. We report transmission electron microscopy (TEM) observation of water phases inside hydrophobic cup-stacked CNTs exposed to high vacuum. Unexpectedly, we observed stable water morphologies beyond surface-tension dominance, including nanometer thin free ...

Durability Investigation of Cup-Stacked Carbon Nanotubes Supported Pt as PEMFC Catalyst

ECS Transactions, 2006
The durability of Pt supported on cup stacked carbon nanotubes (CSCNTs) was investigated with an accelerated test using cyclic voltammetry as a tool. The loss in electrochemically active surface area is compared with that of an E-TEK Pt/Vulcan XC-72 carbon catalyst. The relatively lesser surface area loss in case of Pt/CSCNT catalyst is attributed

Li@SWCNT and Cup-Stacked Carbon Nanotubes for Dye-Sensitezed Solar Cells

ECS Meeting Abstracts, 2015
Carbon Nanotubes (CNTs) are extensively studied for energy applications, mainly as additives in composite electrodes to promote electric and thermal conductivity, reinforce the mechanical strength, and enhance the flexibility and performance. Also, introduction of this nanomaterial into the semiconductors electrodes can reduce the resistance of the ...

A facile approach to prepare porous cup-stacked carbon nanotube with high performance in adsorption of methylene blue

Journal of Colloid and Interface Science, 2015
Novel porous cup-stacked carbon nanotube (P-CSCNT) with special stacked morphology consisting of many truncated conical graphene layers was synthesized by KOH activating CSCNT from polypropylene. The morphology, microstructure, textural property, phase structure, surface element composition and thermal stability of P-CSCNT were investigated by field ...

Near‐Infrared Light‐Driven CO₂ Reduction on Cup‐Stacked Carbon Nanotubes

Angewandte Chemie
AbstractCarbon nanotubes feature one‐dimensional nature of collective excitations, wherein strong confinement of surface plasmons severely hinders the liberation of hot electrons (HEs), posing grand challenges for their utilization in photochemistry.

Mechanical and shape recovery properties of shape memory polymer composite embedded with cup-stacked carbon nanotubes

Journal of Intelligent Material Systems and Structures, 2013
This study investigated the mechanical and shape recovery properties of a styrene-based shape memory polymer composite reinforced by cup-stacked carbon nanotubes. Due to their unique morphology, cup-stacked carbon nanotubes could be well dispersed in the polymer matrix and offer remarkable benefits in the load transfer between the reinforcement ...

Free-Standing Nitrogen-Doped Cup-Stacked Carbon Nanotube Mats for Potassium-Ion Battery Anodes

ACS Applied Energy Materials, 2018
Free-standing nitrogen-doped cup-stacked carbon nanotube (NCSCNT) mats were synthesized and tested as anodes for potassium-ion batteries (KIBs). The edge-open structure character of the NCSCNTs allows a facile insertion of K+ ions into the carbon nanotubes.
