Summary: By introducing porous boron nitride into ionic liquids, the efficiency of sulfur extraction from fuel oil can be improved. Using m-BN-PIL as an extractant under optimized conditions achieves desulfurization performances of 59.2% and 61.8% for dibenzothiophene and 4-methyldibenzothiophene, respectively. After four stepwise extractions, the extraction efficiency over dibenzothiophene reaches 98.2%, achieving deep desulfurization of fuel oil.

Summary: A metal-free N-hydroxyphthalimide/hexagonal boron nitride (NHPI/h-BN) catalytic system was developed for deep oxidative desulfurization (ODS) of fuel oils. The loading of NHPI on h-BN not only improves the dispersion and utilization of NHPI, but also enhances the catalytic performance. The NHPI/h-BN catalyst, together with azodiisobutyronitrile (AIBN) as the metal-free initiator, achieves a 95% conversion of dibenzothiophene (DBT) under specific reaction conditions. The heterogenization process facilitates the regeneration of the catalyst, with >94% DBT conversion after being recycled seven times.

Summary: Heteroatom doping is an effective strategy to improve adsorbents' performance. A comparative study of halogen-doped hexagonal boron nitride materials using DFT and quantum analytic methods shows that the doping stability is related to specific sites with edge_B being the most stable. Higher content of halogen-doped h-BN also leads to improved desulfurization performance due to additional X...H-C hydrogen bonding interactions while maintaining pi-pi interactions.

Summary: In this study, we found that hexagonal boron nitride (h-BN) demonstrates good selectivity and activity in the oxidative dehydrogenation reaction of n-hexane. Low temperatures and oxygen-rich environments favor the selective hydrogen abstraction from C-H bonds, and the presence of gas phase free radicals improves the reaction rate. Additionally, an anomalous relationship exists between the conversion of n-hexane and reaction temperature.

Summary: A series of mesoporous NiMo/LaAlOx catalysts with different La contents were synthesized using a solvent evaporation-induced self-assembly method. It was found that the incorporation of La affected the electronic structure and morphology of the NiMoS active phase. A lower amount of La resulted in improved catalytic activity by promoting the formation of the Type II NiMoS phase. However, higher La incorporation led to the generation of inactive phases and a decrease in the proportion of the NiMoS active phase.

Summary: Grain boundaries can provide highly active surfaces in catalysts, but they are often ignored due to structural variations and design difficulties. This study proposes a novel strategy to prepare nickel molybdate with rich grain boundaries (RGB-NMO). The optimized morphology of RGB-NMO increases the exposure of active sites and facilitates mass transfer in the oxidative desulfurization reaction. Moreover, the engineered grain boundaries can modulate the atomic composition and electronic structure, leading to enhanced hydrogen peroxide activation capacity. The synthesized RGB-NMO demonstrates attractive desulfurization efficiency and cycling stability, providing inspiration for the design of functional materials for efficient ODS treatment.

Summary: Developing efficient catalysts for aerobic oxidation desulfurization has always been a promising technology for purifying diesel fuels. Platinum (Pt) catalysts show potential performance for the selective oxidation of sulfides, although the scarcity and high cost of Pt limit its large-scale development. Alloying Pt is considered to be an effective strategy to reduce the platinum load and increase the high catalytic activity. The researchers successfully prepared highly dispersed PtFe nanoalloys coupled with defect-rich W18O49 nanomaterials, which showed excellent yields of up to 99% for 4,6-dimethyldibenzothiophene.
