From days to hours: A faster way to make a promising new catalyst
Scientists have discovered a faster, more sustainable method for making metal-encapsulated covalent organic frameworks (COFs), materials that have the potential to play a crucial role in catalysis, energy storage, and chemical sensing......»»
Cobalt ions, not covalent organic frameworks themselves, drive catalytic activity, study finds
Covalent organic frameworks (COFs) are less stable as catalysts than previously thought but remain highly active. COFs are promising designer catalysts, for example for the sustainable production of chemicals and fuels. Their properties can be adjust.....»»
