WebJul 15, 2024 · Here, we employ density functional theory to investigate the interfaces of a model carboxylate group, CH 3 COO, on the coinage metal surfaces and clusters. We found that μ2 -CH 3 COO is the most preferred binding mode on the three M (111) surfaces (M = Cu, Ag, and Au), while μ3 -CH 3 COO is also stable on Cu (111) and Ag (111). Webless energy. Coinage metals (copper, silver, and gold) are often found as important components of most catalysts and are known for their high activity and important properties. Thus the demand for research on this topic is continuously increasing. This Special Issue aims to cover several aspects of the usage of Cu, Ag and Au as catalysts for
WebJul 28, 2024 · The possibility of H 2 storage investigated by a thorough theoretical study of the reaction performed between two coinage metal hydrides MH (M=Cu, Ag and Au, homo and heterodimers) is the aim of this study. The energy profiles, the characteristics of the formed complexes and the nature of the established interactions were been discussed. WebCu was one of the earliest metals to be exploited and is still considered as one of the important metals because of its excellent properties such as ductility, malleability, and conductivity.
