Summary: Copper nanoparticles are successfully confined in ordered mesopores of ordered mesoporous carbon (OMC) with controlled sizes, leading to enhanced catalytic activity. Decreasing the mesopore size strengthens the interaction between copper and carbon surface, promoting electron shifts from carbon surface to copper nanoparticles, and thus facilitating the reduction of CuO to active Cu2O species. This concept can be applicable to the preparation of other metal-supported catalysts.

Summary: The study compared Pt particles deposited on 3D cage-type SBA-16 and 2D-hexagonal SBA-15 mesoporous silica for the total oxidation of m-xylene and methanol. Pt particles on SBA-15 showed better catalytic performance due to their stronger ability to dissociate reaction molecules and produce smaller particles, enhancing catalytic activity in oxidation reactions. This indicates that the support of SBA-15 leads to notable CO formation while also exhibiting high activity for methanol oxidation.

Summary: In this study, PtCo alloys catalysts supported on multiwalled carbon nanotubes (MWCNTs) were prepared with improved methanol oxidation reaction (MOR) properties and anti-CO poisoning ability. The Pt1Co3@NC/MWCNTs sample with moderate Co2+ feeding content showed a 1.93-fold enhancement in MOR mass activity compared to commercial Pt/C catalyst. Additionally, it displayed a lower CO oxidation onset potential. The improvements in MOR activity, durability, and anti-CO poisoning ability were attributed to the moderate surface compositions, optimal electronic interaction, and the protection of N-doped carbon (NC) shells. This study provides a new direction for the design and fabrication of highly efficient electrocatalysts for DMFCs applications.

Summary: Pseudocapacitive behavior is a highly studied topic in the field of electrochemistry. Accurately distinguishing between capacitive, pseudocapacitive, and battery behavior is a challenging task. Moreover, the discovery of non-Faraday capacitive charge storage mechanism in non-carbon-based materials has posed difficulties in defining the electrochemical behavior of newly discovered materials. This study presents the first report on the pseudocapacitance behavior of sanmar-tinite (ZnWO4), showing ideal rectangular cyclic voltammetry curves and isosceles triangle galvanostatic charge/discharge curves. The calculated value of b, 0.88, further confirms that the kinetic process is controlled by surface capacitance.

Summary: Ti3C2-MXene has been widely studied for energy storage applications due to its adjustable surface chemistry, excellent electronic conductivity, and unique layered structure. However, the diffusion kinetics of alkali metal ions in Ti3C2 is limited by the interlayer spacing. In this study, a diphenic acid (DHA) molecular welding strategy is used to prepare DHA-Ti3C2 with enlarged interlayer spacing, improving ion diffusion rate and structure stability. DHA-Ti3C2 exhibits high rate capability and long-term cycle stability with specific capacities of 444 mAh g(-1) and 156 mAh g(-1) after 200 cycles and 1700 cycles in Li+/Na+ batteries, respectively. This study provides a strategy to efficiently tune the layered structure of 2D materials for optimal alkali metal ions storage performance.

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.
