Direct observation of noble metal nanoparticles transforming to thermally stable single atoms.

TL;DR: An unexpected phenomenon that noble metal nanoparticles can be transformed to thermally stable single atoms (Pd, Pt, Au-NPs) above 900 °C in an inert atmosphere and exhibited even better activity and selectivity than nanoparticles for semi-hydrogenation of acetylene.
Journal ArticleDOI

Copper atom-pair catalyst anchored on alloy nanowires for selective and efficient electrochemical reduction of CO 2

TL;DR: A catalyst that features two adjacent copper atoms that work together to carry out the critical bimolecular step in CO2 reduction is reported, which results in a Faradaic efficiency for CO generation above 92%, with the competing hydrogen evolution reaction almost completely suppressed.
Journal ArticleDOI

Accurate Band Gaps for Semiconductors from Density Functional Theory

TL;DR: In this article, the authors show that for the parent compound of the promising CIGS Cu(InxGa1−x)Se2 solar devices, local density and generalized gradient approximation (GGA) density functionals generally underestimate band gaps for semiconductors and sometimes incorrectly predict a metal.
Journal ArticleDOI

Schottky-Barrier-Free Contacts with Two-Dimensional Semiconductors by Surface-Engineered MXenes

TL;DR: Understanding of the correlation between surface chemistry and electronic/transport properties of 2D materials is enhanced, and predictions for improving 2D electronics are given.
