TL;DR: In this paper, the atomically dispersed nickel on nitrogenated graphene was identified as an efficient and durable electrocatalyst for CO2 reduction based on operando X-ray absorption and photo-electron spectroscopy measurements, and the monovalent Ni(i) atomic center with a d9 electronic configuration is identified as the catalytically active site.

TL;DR: The charge transfer from the CuO support to single Au atoms is confirmed to play a key role in tuning the activity for CO oxidation.

TL;DR: A simple method is reported for the growth of quasi-free-standing single layer blue phosphorus on tellurium functionalized Au(111) by using black phosphorus as the precursor, which forms triangular structures arranged hexagonally on theTellurium layer.

TL;DR: In this article, the authors identify Ni-O phases as important intermediates in a modeled dry (CO2) reforming of methane catalyzed by Ni (111), based on results from in operando near ambient pressure X-ray photoelectron spectroscopy (NAP-XPS) experiments, corroborated by low energy electron diffraction (LEED) and scanning tunneling microscopy (STM) measurements.

TL;DR: The superb performance of the hierarchical porous δ-MnO2 nanoboxes, together with a convenient fabrication method, presents an alternative to develop advanced cathode catalysts for the Li-O2 battery.
