Summary: Active components play different roles in improving catalytic performance due to their different physicochemical properties. In this study, a series of SmCeMn/Ti catalysts with different metal components exposed on the outer surface were synthesized to study their catalytic roles for NH3-SCR. The results showed that Mn contributed more B-acid sites and Mn4+, facilitating NO conversion. Ce generated a large amount of Mn4+ through a strong redox reaction with Mn3+ and generated abundant oxygen vacancies during the reaction process due to its strong oxygen storage-release capacity, while Sm acted as a sacrifice site for electron transfer with Mn to improve sulfur resistance.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
