Summary: The evolution of model catalyst systems has progressed from single-crystal surfaces to two-dimensional and three-dimensional systems, mimicking the properties of nanoparticles in industrial catalysts. Ordered mesoporous carbon (OMC) materials have unique structures that enable Knudsen diffusion, metal dispersion, and metal embedment, and play important roles in catalysis and other applications. This review provides an introduction to the synthesis routes of OMC-supported metal or metal oxide catalysts and systematically summarizes the mass transfer, reactant chemisorption, discrimination of active species, and catalytic reaction mechanism of these catalysts, with a focus on the advantages of catalysis occurring inside mesopores. Understanding these factors helps in controlling catalytic reactions and designing long-lasting industrial catalysts.

Summary: Oxoiron(IV) species are important intermediates in the Fe-based Fenton-like process, and their reactivity is strongly influenced by their ligands. In this study, a highly reactive sulfur ligand coordinated Fe species was constructed using MoS2 as an inorganic host material. The interaction between doped Fe and the MoS2 lattice in the formation of oxoiron(IV) was investigated. Fe-MoS2 showed significant Fenton-like reactivity and accumulation of oxoiron(IV) species. Quenching experiments revealed the predominant role of oxoiron(IV) species in the Fe-MoS2/H2O2 Fenton-like system. Furthermore, oxoiron(IV) species can transform into reactive oxygen species, further promoting the Fenton-like reaction.

Summary: In this study, a graphene network loaded with cobalt metal nanoparticles was used to coat SiO 2 porous hollow spheres, forming SiO 2 @rGO-Co composite material. The composite material with porous structure and graphene network can shorten the lithium-ion diffusion distance, improve conductivity, and enhance the electrochemical activity of SiO 2 while reducing the volume expansion of the anode during cycling. Additionally, the nano-scale cobalt metal particles dispersed on graphene catalyze the conversion reaction of SiO 2 and activate the locked Li + in Li 2 O through a reversible reaction, thus increasing the charge and discharge capacity of the anode. The capacity of SiO 2 @rGO-Co reaches 370.4 mAh/g after 100 cycles, which is 6.19 times higher than that of pure SiO 2 (59.8 mAh/g) under the same conditions. Furthermore, the structure also exhibits excellent cycle stability with a volume expansion rate of only 13.0% after 100 cycles at a current density of 0.1 A/g.

Summary: In this study, AlN/YAlO3 composites with different YAlO3 contents were prepared, and the impact of YAlO3 content on the mechanical properties and thermal shock resistance of the composites was investigated. Results showed that the addition of 3 wt% and 5 wt% YAlO3 improved the densification and the grain refinement of AlN, leading to improved flexural strength and fracture toughness of the composites. Moreover, the thermal shock resistance of the composites was significantly improved due to various strengthening mechanisms such as crack deflection, crack branching, and microcrack toughening.

Summary: A hierarchical functionalization strategy for sulfur species in lithium-sulfur batteries has been proposed to address issues of low sulfur utilization and uncontrollable dendritic growth. The strategy involves the use of a catalytic host cathode and a multifunctional interlayer to promote rapid catalytic conversion of sulfur species and enhance the anchoring, diffusion, and conversion of lithium polysulfides. The batteries equipped with this strategy exhibit high reversible capacity, superior cycling stability, and a favorable specific capacity, demonstrating potential for practical application.
