Journal ArticleDOI
Progress and Perspectives of Electrochemical CO2 Reduction on Copper in Aqueous Electrolyte
Stephanie A. Nitopi,Erlend Bertheussen,Søren Bertelsen Scott,Xinyan Liu,Albert K. Engstfeld,Albert K. Engstfeld,Sebastian Horch,Brian Seger,Ifan E. L. Stephens,Ifan E. L. Stephens,Karen Chan,Karen Chan,Christopher Hahn,Christopher Hahn,Jens K. Nørskov,Jens K. Nørskov,Jens K. Nørskov,Thomas F. Jaramillo,Thomas F. Jaramillo,Ib Chorkendorff +19 more
TL;DR: A broad and historical view of different aspects and their complex interplay in CO2R catalysis on Cu is taken, with the purpose of providing new insights, critical evaluations, and guidance to the field with regard to research directions and best practices.
Journal ArticleDOI
Designing an improved transition metal phosphide catalyst for hydrogen evolution using experimental and theoretical trends
Jakob Kibsgaard,Jakob Kibsgaard,Charlie Tsai,Charlie Tsai,Karen Chan,Jesse D. Benck,Jens K. Nørskov,Jens K. Nørskov,Frank Abild-Pedersen,Thomas F. Jaramillo,Thomas F. Jaramillo +10 more
TL;DR: In this article, the authors demonstrate a combined experimental-theoretical approach to synthesize different transition metal phosphides and compare experimentally determined HER activities with the hydrogen adsorption free energies, calculated by density functional theory.
Journal ArticleDOI
Electrochemical Ammonia Synthesis-The Selectivity Challenge
Aayush R. Singh,Brian A. Rohr,Jay A. Schwalbe,Matteo Cargnello,Karen Chan,Thomas F. Jaramillo,Ib Chorkendorff,Jens K. Nørskov +7 more
Journal ArticleDOI
Theoretical insights into a CO dimerization mechanism in CO2 electroreduction
TL;DR: DFT simulations that demonstrate the ability of Cu to catalyze CO dimerization in CO2 and CO electroreduction with cations other than H(+) are presented, a finding that is consistent with the experimentally observed pH independence of C2 formation on Cu.
Journal ArticleDOI
Promoter Effects of Alkali Metal Cations on the Electrochemical Reduction of Carbon Dioxide.
Joaquin Resasco,Leanne D. Chen,Ezra L. Clark,Ezra L. Clark,Charlie Tsai,Charlie Tsai,Christopher Hahn,Christopher Hahn,Thomas F. Jaramillo,Thomas F. Jaramillo,Karen Chan,Karen Chan,Alexis T. Bell,Alexis T. Bell +13 more
TL;DR: Density functional theory calculations show that the alkali metal cations influence the distribution of products formed as a consequence of electrostatic interactions between solvated cations present at the outer Helmholtz plane and adsorbed species having large dipole moments.
