Summary: In this study, a series of Pr6O11 catalysts were developed by CTAB-assisted coprecipitation method and their catalytic performances for soot oxidation and NOx adsorption were investigated. The Pr6O11 catalysts exhibited excellent catalytic activities for both soot oxidation and NOx adsorption at low temperature, which was attributed to their relatively large surface area, strong NO oxidation ability, and high intrinsic activity. The presence of NO was found to promote the soot oxidation, and the possible mechanism of the soot oxidation reaction process was explored using in situ DRIFTS.

Summary: Sub-10 nm 2D SnO2-ZnO heterostructures were constructed on Au-modified SiO2/Si wafers using atomic layer deposition (ALD) for high-performance electrochemical supercapacitors (ESCs). The heterostructure electrode exhibited pseudocapacitive-type Faradaic redox reactions with good reversibility. It achieved a high specific capacitance (Cs) of 538.90 F g-1 at a scan rate and current density of 10 mV s-1 and 8.0 A g-1, respectively. The high energy storage capacity and excellent electrochemical robustness of the 2D heterostructure electrode were attributed to the nanoscale thickness, improved infiltration and intercalation/deintercalation, and enhanced redox activity of the heterostructure.

Summary: This study investigates the phenomenon of the graphitization of free carbon in polymer-derived ceramics (PDCs) and uncovers the crucial role of surface/interface interactions in regulating carbon and its properties. Due to the enrichment behavior of free carbon in the near-surface/interface region, PDCs exhibit highly abnormal properties, such as the behavior of the current and the edge effect. These surface/interface interactions are of great significance for the applications of PDCs.
