The role of long-lived oxygen precursors on AuM alloys (M = Ni, Pd, Pt) in CO oxidation
文献信息

Gold alloys have been reported to be active in very low temperature oxidation of CO. The reasons for the better performance of AuNi with respect to Ni(111) surfaces were reported recently by indicating an active role of gold. Our results show that for this alloy, the CO oxidation molecular channel is responsible for the low temperature performance but the remaining oxygen on the surface is tightly bound and the process is not catalytic at low to room temperatures. The contribution from the associative path is also improved for the rest of the series: AuPd and AuPt. Only in the latter case, an important reduction of the light-off temperature of the catalytic path is observed.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
