TL;DR: It is shown that cobalt(II) oxide (CoO) nanoparticles can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5% and that the high photocatalytic activity of the nanoparticles arises from a significant shift in the position of the band edge of the material.
Journal ArticleDOI
Surface Structure at the Ionic Liquid−Electrified Metal Interface
TL;DR: The results present a view of the ionic liquid-metal electrode interface having a very thin "double layer" structure where the ions form a single layer at the surface to screen the electrode charge, and raise many other fundamental questions as to the detailed nature of the interfacial structure and interpretations of both electrochemical and spectroscopic data.
Journal ArticleDOI
Influence of Water on the Surface of Hydrophilic and Hydrophobic Room-Temperature Ionic Liquids
TL;DR: Under low water conditions the plane of the imidazolium ring remains parallel to the surface for both types of ionic liquid, however, at high water content the ring will reorient to along the surface normal for the hydrophobic ionicLiquid but remain parallel toThe surface for the Hydrophilic one.

TL;DR: In this paper, a complete picture of perovskite from initial physical uptake of water molecules to final chemical transition to its monohydrate MAPbI3·H2O is obtained with in situ infrared spectroscopy, mass monitoring, and X-ray diffraction.
Journal ArticleDOI
Influence of Water on the Orientation of Cations at the Surface of a Room-Temperature Ionic Liquid: A Sum Frequency Generation Vibrational Spectroscopic Study
TL;DR: In this article, the authors used vibrational spectroscopy to determine the orientation of the cations in a room-temperature ionic liquid at the air−liquid interface.
