Journal ArticleDOI
Achieving Highly Efficient, Selective, and Stable CO2 Reduction on Nitrogen-Doped Carbon Nanotubes.
Jingjie Wu,Ram Manohar Yadav,Mingjie Liu,Pranav P. Sharma,Chandra Sekhar Tiwary,Lulu Ma,Xiaolong Zou,Xiao-Dong Zhou,Boris I. Yakobson,Jun Lou,Pulickel M. Ajayan +10 more
TL;DR: It is reported that carbon nanotubes, doped with nitrogen to form resident electron-rich defects, can act as highly efficient and, more importantly, stable catalysts for the conversion of CO2 to CO.
Journal ArticleDOI
A metal-free electrocatalyst for carbon dioxide reduction to multi-carbon hydrocarbons and oxygenates
Jingjie Wu,Sichao Ma,Jing Sun,Jake I. Gold,Chandra Sekhar Tiwary,Byoungsu Kim,Byoungsu Kim,Lingyang Zhu,Nitin Chopra,Ihab N. Odeh,Robert Vajtai,Aaron Z. Yu,Raymond Luo,Jun Lou,Guqiao Ding,Paul J. A. Kenis,Paul J. A. Kenis,Pulickel M. Ajayan +17 more
TL;DR: It is reported that nanometre-size N-doped graphene quantum dots (NGQDs) catalyse the electrochemical reduction of carbon dioxide into multi-carbon hydrocarbons and oxygenates at high Faradaic efficiencies, high current densities and low overpotentials.
Journal ArticleDOI
Nitrogen‐Doped Carbon Nanotube Arrays for High‐Efficiency Electrochemical Reduction of CO2: On the Understanding of Defects, Defect Density, and Selectivity
Pranav P. Sharma,Jingjie Wu,Ram Manohar Yadav,Mingjie Liu,Christopher J. Wright,Chandra Sekhar Tiwary,Boris I. Yakobson,Jun Lou,Pulickel M. Ajayan,Xiao-Dong Zhou +9 more
TL;DR: Nitrogen-doped carbon nanotubes have been considered as a promising electrocatalyst for carbon-dioxide-reduction reactions, but two fundamental chemistry questions remain obscure: what are the active centers with respect to various defect species and what is the role of defect density on the selectivity of NCNTs?
Journal ArticleDOI

TL;DR: It is demonstrated that photogenerated electrons can be transferred from hematene to titania despite a band alignment unfavourable for charge transfer, and ferromagnetic ordering and enhanced photocatalytic activity are shown.
Journal ArticleDOI
