Origin of the Overpotential for Oxygen Reduction at a Fuel-Cell Cathode
Jens K. Nørskov,Jan Rossmeisl,and Ashildur Logadottir,L. Lindqvist,John R. Kitchin,Thomas Bligaard,Hannes Jónsson +6 more
TL;DR: In this paper, the stability of reaction intermediates of electrochemical processes on the basis of electronic structure calculations was analyzed and a detailed description of the free energy landscape of the electrochemical oxygen reduction reaction over Pt(111) as a function of applied bias was presented.

Identification of active edge sites for electrochemical H2 evolution from MoS2 nanocatalysts.
Thomas F. Jaramillo,Kristina Pilt Jørgensen,Jacob Lindner Bonde,Jane Hvolbæk Nielsen,Sebastian Horch,Ib Chorkendorff +5 more
TL;DR: The active site for hydrogen evolution, a reaction catalyzed by precious metals, on nanoparticulate molybdenum disulfide (MoS2) is determined by atomically resolving the surface of this catalyst before measuring electrochemical activity in solution.

Enhancing Hydrogen Evolution Activity in Water Splitting by Tailoring Li+-Ni(OH)2-Pt Interfaces
Ram Subbaraman,Dusan Tripkovic,Dusan Strmcnik,Kee-Chul Chang,Masanobu Uchimura,Arvydas P. Paulikas,Vojislav R. Stamenkovic,Nenad M. Markovic +7 more
TL;DR: It is found that a controlled arrangement of nanometer-scale Ni(OH)2 clusters on platinum electrode surfaces manifests a factor of 8 activity increase in catalyzing the hydrogen evolution reaction relative to state-of-the-art metal and metal-oxide catalysts.
