Unique copper nanocluster design increases selectivity in COâ‚‚ reduction
Detailed structures of two different Cu14 NCs protected by two different thiols investigated in this study. These NCs exhibit various intercluster interactions that shape the stability and reaction selectivity of the electrochemical CO2 reduction reaction. Credit: Small (2024). DOI: 10.1002/smll.202409910 The humble copper (Cu) may not have the allure of gold or silver, but its incredible versatility makes it invaluable…

Theoretical framework reveals how reaction conditions tune catalyst selectivity
Schematic representation of the theoretical framework: Starting with a computational model of the prepared catalyst, scientists use density functional theory calculations and kinetic modeling to map phase changes under different reaction conditions. This approach allows you to discover how reaction conditions affect the active phase of a catalyst and how reaction conditions can be used to influence catalyst performance. Credit:…

Physicists use selenium doping to achieve high selectivity in nanostructures
Scanning tunneling microscope image of the reaction pathway of mTBPT on a Cu(111) substrate, showing the transition from a random metal-organic structure before selenium doping to a well-ordered, crystalline, two-dimensional metal-organic nanostructure after doping. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-47614-9 Physicists at the National University of Singapore (NUS) have used flexible precursors and selenium doping to achieve controlled conformations of…
