Suppressing the Pd-C interaction through B-doping for highly efficient oxygen reduction
Cai Zhang,Shansheng Yu,Yanan Xie,Wei Zhang,Kang Zheng,Nicholas E. Drewett,Seung Jo Yoo,Zizhun Wang,Lidong Shao,Hongwei Tian,Jin-Gyu Kim,Weitao Zheng +11 more
TL;DR: In this paper, Boron (B)-doping enables reversing such structural evolution and suppressing the Pd-C interaction, which literates Pd from the interaction, increases its electrochemical specific surface area (ECSA), and contributes to the highly efficient ORR performance in alkaline solution.

Oxidative dehydrogenation reaction of short alkanes on nanostructured carbon catalysts: a computational account
XiaoYing Sun,Peng Han,Bo Li,ShanJun Mao,Tianfu Liu,Tianfu Liu,Sajjad Ali,Zan Lian,Zan Lian,Dang Sheng Su +9 more
TL;DR: Recent progress from first principles computational studies is presented for catalytic properties of nanostructured carbon catalysts in the oxidative dehydrogenation (ODH) reaction of short alkanes and extensive calculations suggest that the BEP relation is applicable for the doped nanostructure carbon catalyts.

First-Principles Modeling in Heterogeneous Electrocatalysis
TL;DR: The computational hydrogen electrode method as discussed by the authors has been widely used in the literature to account for the inflow and outflow of electrons from the electrode as electrochemical reactions proceed, which has been greatly assisted by the development of density functional theory within the grand canonical framework.

Electric Field Effect in Atomically Thin Carbon Films
Kostya S. Novoselov,Andre K. Geim,Sergey V. Morozov,Da Jiang,Y. Zhang,S. V. Dubonos,Irina V. Grigorieva,A. A. Firsov +7 more
TL;DR: Monocrystalline graphitic films are found to be a two-dimensional semimetal with a tiny overlap between valence and conductance bands and they exhibit a strong ambipolar electric field effect.
