Journal ArticleDOI
Alkali-stabilized Pt-OHx species catalyze low-temperature water-gas shift reactions.
Yanping Zhai,Danny Pierre,Rui Si,Weiling Deng,Peter Ferrin,Anand Udaykumar Nilekar,Guowen Peng,Jeffrey A. Herron,David C. Bell,Howard Saltsburg,Manos Mavrikakis,Maria Flytzani-Stephanopoulos +11 more
TL;DR: Alkali ions added in small amounts activate platinum adsorbed on alumina or silica for the low-temperature water-gas shift (WGS) reaction (H2O + CO → H2 + CO2) used for producing H2.
Journal ArticleDOI
Mechanism of ferromagnetism in nitrogen-doped ZnO: First-principle calculations
TL;DR: Based on first-principle calculations, ZnO doped by a nonmagnetic $2p$ light element (N) is predicted to be ferromagnetic as mentioned in this paper.
Journal ArticleDOI
Ferromagnetism in 2p Light Element-Doped II-oxide and III-nitride Semiconductors
TL;DR: In this article, II-oxide and III-nitride semiconductors doped by non-magnetic 2p light elements are investigated as potential dilute magnetic semiconductor (DMS) materials.
Journal ArticleDOI
Water-mediated proton hopping on an iron oxide surface.
Lindsay R. Merte,Guowen Peng,Ralf Bechstein,Felix Rieboldt,Carrie A. Farberow,Lars C. Grabow,Wilhelmine Kudernatsch,Stefan Wendt,Erik Lægsgaard,Manos Mavrikakis,Flemming Besenbacher +10 more
TL;DR: A high-resolution, high-speed scanning tunneling microscopy study of the diffusion of H atoms on an FeO thin film shows a proton-transfer mechanism that proceeds via an H3O+-like transition state, which differs from that observed previously for rutile TiO2(110), where water dissociation is a key step in proton diffusion.
Journal ArticleDOI
Improving Electrocatalysts for O2 Reduction by Fine-Tuning the Pt−Support Interaction: Pt Monolayer on the Surfaces of a Pd3Fe(111) Single-Crystal Alloy
Wei Ping Zhou,Xiaofang Yang,Miomir Vukmirovic,Bruce E. Koel,Jiao Jiao,Guowen Peng,Manos Mavrikakis,Radoslav Adzic +7 more
TL;DR: The density functional theory studies suggest that the observed enhancement of ORR activity originates mainly from the destabilization of OH binding and the decreased Pt-OH coverage on the Pt/Pd/P d(3)Fe(111) surface.
