Gold carbonate

WebOct 11, 2008 · Abstract. We report the enhanced formation and decomposition of carbonate (CO 3 ↔ CO 2 + O a) from the reaction of C 18 O 2 preadsorbed on Au (111) with an 16 O atomic beam. The amount of formed carbonate increases significantly (by a factor of ∼4) compared to thermally accommodated C 18 O 2 and 16 O a coadsorbed on the Au (111) … WebFeb 22, 2011 · Gold and silver share a number of chemical and physical properties.
