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 ...

What are Metal Oxide Nanoparticles? Metal oxide nanoparticles are a class of nanomaterials composed of metal cations bonded to oxygen anions, with particle sizes ranging from 1 to 100 nanometers.

A mix of equal portions of metal ion precursors on a film of graphene oxide (left) are subjected to a photoflash from a Xenon lamp. Heated to more than 1,000 K, the precursors transform into ...

Gold nanoparticles, particles less than five ... The effect is pronounced when they are mounted on metallic oxides like cobalt oxide, which are more likely to undergo the opposite reaction i.e ...
