Herein we show that primary amine ligands on CuNPs can be exchanged with thiols without etching the CuNP, and report the unexpected findings of an investigation into the stability of isolated CuNPs towards oxidation in air when capped with the eight different thiolate ligands. The experiment design...

The tribological, oxidation and thermal conductivity properties of an engine ...
The increase in catalyst concentration increased the number of reactive sites and enhanced the light absorption for photocatalysis [151]. The higher concentrations of the catalyst may result in light-scattering and screening effects due to high opacity caused by an excess catalyst which compromised ...
After oxidation of the products Cu and Cu2O back to CuO, the kinetics in subsequent cycles of chemical looping oxidation of H2 could be approximated by those in the first. Interestingly, the carrier was found to react at temperatures as low as 300 °C. The influence of the number ...
Metal-organic framework derived hollow CuO/CeO2 nano-sphere: To expose more highly dispersed Cu-O-Ce interface for enhancing preferential CO oxidation Derivation of CuO/CeO 2 catalyst from metal-organic framework (MOF) precursor is able to facilitate the dispersion of active sites, resulting in an...
LaCoO3 and LaCo0.8Cu0.2O3 perovskite-type oxides prepared by the polymerizable complex route were obtained as single phase and investigated in the partial oxidation of methane through temperature-programmed surface reactions (TPSR). Characterizations were carried out before and after the reactions under ...
Given that the step edge is vulnerable to oxidation because surface steps act as the dominant source of Cu adatoms for oxide growth on surface terraces2,11, oxidation resistance requires that surface step edges are avoided6,12,13. In this regard, the close-packed Cu(111) surface is superior...
