Baby boomer game. Copper’s Virus-Killing Powers Were Known Even to the Ancients The SARS-CoV-2 virus endures for days on plastic or metal but disintegrates soon after landing on copper surfaces. Here we report a catalyst that features two adjacent copper atoms, which we call an 'atom-pair catalyst', that work together to carry out the critical bimolecular step in CO 2 reduction. The atom-pair catalyst features stable Cu 1 0 -Cu 1 x+ pair structures, with Cu 1 x+ adsorbing H 2 O and the neighbouring Cu 1 0 adsorbing CO 2, which thereby.
