Journal ArticleDOI
In Search of the Active Site in Nitrogen-Doped Carbon Nanotube Electrodes for the Oxygen Reduction Reaction
TL;DR: In this paper, a series of vertically aligned carbon nanotubes (VA-CNTs) with a surface nitrogen concentration of 0, 4.3, 5.6, 8.4, and 10.7 atom % is prepared by the alumina template technique and characterized with XRD, Raman spectroscopy, SEM, and XPS.
Journal ArticleDOI
LiNi1/3Co1/3Mn1/3O2–Graphene Composite as a Promising Cathode for Lithium-Ion Batteries
TL;DR: The results indicate the better electrochemical performance of the LiNi(1/3)Co(1-1-3)Mn( 1/3-O(2)-graphene composite in terms of high discharge capacity, good rate capability, and good cycling performance compared to LiNi (1/2)Co (1-2-O)(2-2), which is attributed to a decrease in the charge-transfer resistance.
Journal ArticleDOI
Oxidation of methanol on platinum, ruthenium and mixed Pt–M metals (M=Ru, Sn): a theoretical study
TL;DR: A relativistic density-functional study of the dehydrogenation of CH3OH and H2O on pure platinum, ruthenium, and mixed Pt-M (M=Ru, Sn) metals is reported in this paper.
Journal ArticleDOI
Synthesis and electrocatalytic oxygen reduction activity of graphene-supported Pt3Co and Pt3Cr alloy nanoparticles
TL;DR: Graphene-supported Pt and Pt3M (M = Co and Cr) alloy nanoparticles are prepared by ethylene glycol reduction method and characterized with X-ray diffraction and transmission electron microscopy as discussed by the authors.
Journal ArticleDOI
Open-shell relativistic coupled-cluster method with Dirac-Fock-Breit wave functions: Energies of the gold atom and its cation
TL;DR: The CCSD approximation is implemented, which includes single and double virtual excitations in a self-consistent manner, incorporating therefore the effects of the Coulomb and Breit interactions to all orders in these excitations.
