Journal ArticleDOI
Nitrogen-doped carbon nanotube arrays with high electrocatalytic activity for oxygen reduction.
TL;DR: It is reported that vertically aligned nitrogen-containing carbon nanotubes (VA-NCNTs) can act as a metal-free electrode with a much better electrocatalytic activity, long-term operation stability, and tolerance to crossover effect than platinum for oxygen reduction in alkaline fuel cells.
Journal ArticleDOI
Mechanisms of Oxygen Reduction Reaction on Nitrogen-Doped Graphene for Fuel Cells
Lipeng Zhang,Zhenhai Xia +1 more
TL;DR: In this paper, the authors used density functional theory (DFT) to demonstrate that the oxygen reduction reaction (ORR) on N-doped graphene is a direct fourelectron pathway, which is consistent with the experimental observations.
Journal ArticleDOI
BCN Graphene as Efficient Metal-Free Electrocatalyst for the Oxygen Reduction Reaction
Shuangyin Wang,Lipeng Zhang,Zhenhai Xia,Ajit K. Roy,Dong Wook Chang,Jong-Beom Baek,Liming Dai +6 more
TL;DR: This work has previously prepared vertically aligned nitrogendoped carbon nanotubes as ORR electrocatalysts, which are free from anode crossover and CO poisoning and show a threefold higher catalytic activity and better durability than the commercial Pt/C catalyst.
Journal ArticleDOI
Carbon nanotube arrays with strong shear binding-on and easy normal lifting-off.
TL;DR: This work has created gecko-foot–mimetic dry adhesives that show macroscopic adhesive forces of ∼100 newtons per square centimeter, almost 10 times that of a gecko foot, and a much stronger shear adhesion force than the normalAdhesion force, to ensure strong binding along the shear direction and easy lifting in the normal direction.
Journal ArticleDOI
In Situ Exfoliated, Edge-Rich, Oxygen-Functionalized Graphene from Carbon Fibers for Oxygen Electrocatalysis.
Zhijuan Liu,Zhenghang Zhao,Yanyong Wang,Shuo Dou,Dafeng Yan,Dongdong Liu,Zhenhai Xia,Zhenhai Xia,Shuangyin Wang +8 more
TL;DR: The first example of in situ exfoliated, edge-rich, oxygen-functionalized graphene on the surface of carbon fibers using Ar plasma treatment is successfully prepared and has a higher specific surface area and an increased number of active sites for OER and ORR.
