Nonmetal oxygen vacancies confined under boron nitride for enhanced oxidative dehydrogenation of propane to propene

Qiuwen Liu et al.

Summary: In this study, oxygen vacancies-rich BPO4 hollow spheres covered with few-layer hexagonal boron nitride (BN) were prepared, showing better catalytic activity and selectivity in the oxidative dehydrogenation of propane to propene compared to commercial BN due to the synergistic effect between oxygen vacancies-rich BPO4 and h-BN. Oxygen vacancies enhance propane adsorption while the confined space at the interface weakens propene adsorption, facilitating active site recycling. The confined space and oxygen vacancies also lead to a transformation in the reaction kinetic model.

It's a Gas: Oxidative Dehydrogenation of Propane over Boron Nitride Catalysts

Peter Kraus et al.

Summary: The study suggests that boron nitride catalysts exhibit high selectivity in the oxidative dehydrogenation of propane, which can be modeled reasonably well by a gas-phase conversion mechanism. Water cofeed leads to increased conversion of propane, while dilution of the catalytic bed and variations in the C3H8/O-2 ratio also affect the selectivities of minor species in gas-phase reactions.

Isolated boron in zeolite for oxidative dehydrogenation of propane

Hang Zhou et al.

Summary: Isolated boron in a zeolite framework without B-O-B oligomers exhibits high activity and selectivity for oxidative dehydrogenation of propane (ODHP). The boron-silicon bonding structure hinders boron leaching in a humid atmosphere, enhancing catalyst durability. The -B[OH center dot center dot center dot O(H)-Si](2) structure in borosilicate zeolite serves as the active center for activating oxygen and carbon-hydrogen bonds to catalyze ODHP.

Plasma Tuning Local Environment of Hexagonal Boron Nitride for Oxidative Dehydrogenation of Propane

Zhankai Liu et al.

Summary: The study found that N2-treated hexagonal boron nitride showed remarkable activity with good selectivity towards propane, while O2 treatment led to sintering effect of BOx species which suppressed the catalytic performance.

Highly Selective Carbon-Supported Boron for Oxidative Dehydrogenation of Propane

Lesli O. Mark et al.

Summary: Bulk boron materials, such as hexagonal boron nitride (h-BN), are highly selective catalysts for the oxidative dehydrogenation of propane. Previous attempts to improve productivity by immobilizing boron on silica led to less selective catalysts. Acid-treated, activated carbon-supported boron (B/OAC) prepared via incipient wetness impregnation exhibits equal propylene selectivity and improved productivity compared to h-BN, with oxidized/hydrolyzed boron clustered on the support surface.

Controlled Grafting Synthesis of Silica-Supported Boron for Oxidative Dehydrogenation Catalysis

Melissa C. Cendejas et al.

Summary: The study focused on the controlled grafting synthesis of pinacolborane on amorphous silica, revealing that the silica pretreatment dehydration temperature can control the formation of hydrogen bonds. Thermal treatment under vacuum showed that boron on the silica surface is highly mobile at elevated temperatures, and the catalysts exhibited expected activity. However, the kinetic behavior of these supported catalysts deviates from that of bulk boron materials, prompting further research into reaction kinetics.

Identifying Boron Active Sites for the Oxidative Dehydrogenation of Propane

Huan Yan et al.

Summary: The study discovered that depositing differently sized boronic acids into the micropores of silica supports results in different distributions of surface borate species after calcination. These materials exhibit a wide range of rates in ODHP but similar selectivity, indicating they differ only in the numbers of active sites. The correlation between identified features and catalyst activity confirms hydroxylated nonring boron as the likely active site, providing a target for future catalyst syntheses.
