Gold nanoparticles give an edge in recycling CO2

(Phys.org) —It's a 21st-century alchemist's dream: turning Earth's superabundance of carbon dioxide—a greenhouse gas—into fuel or useful industrial chemicals. Researchers from Brown have shown that finely tuned gold nanoparticles can do the job. The key is maximizing the particles' long edges, which are the active sites for the reaction.
