From COâ‚‚ to acetaldehyde: new copper catalyst offers green alternative to fossil fuel-based processes
Copper cluster catalyst on activated carbon. Credit: Cedric Coolen (EPFL) Acetaldehyde is an important chemical used in the production of everything from perfume to plastics. Currently, its production relies primarily on the petrochemical ethylene. However, growing environmental concerns have pushed the chemical industry to reduce its dependence on fossil fuels, and scientists have been searching for more environmentally friendly ways…

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…

Scientists develop copper depletion strategy for advanced cuprococcal disease treatment
Credit: Chemical Sciences (2024). DOI: 10.1039/D4SC04712E A research team from Nanjing University introduced an innovative approach to copper ptosis treatment by depleting copper levels within tumor cells, challenging the current paradigm focused on copper overproduction. The study, published in the journal Chemical Science, uses mesoporous zinc sulfide (ZnS) nanoparticles as “copper nanoconsumers” to efficiently remove copper ions from cancer cells.…
