Chementator: One less step to make activated carbon with dispersed metal nanoparticles    

Nanostructured microporous carbons containing well-dispersed metal nanoparticles have the potential to improve the performance of fuel cells or catalysis. However, traditional techniques for embedding metal particles in porous carbons (post-synthesis treatment either by impregnation, adsorption, or ion exchange) can lead…
