“…The catalytic hydrogenation of olefins plays an important role in the chemical industry, serving as a pivotal catalytic reaction for the production of diverse transportation fuels including gasoline, diesel, and jet fuel. Jet propellant 10 (JP-10) fuel possesses many advantages such as a high density (0.939 g/ cm 3 ), a low freezing point (−79 °C), and a high calorific value of combustion (39.6 MJ/kg), exhibiting unparalleled performance in contemporary applications. 1 The hydrogenation of dicyclopentadiene (DCPD) to tetrahydrodicyclopentadiene (THDCPD) is a crucial reaction step to obtain JP-10.…”

“…The hydrogenation of dicyclopentadiene (DCPD) to tetrahydrodicyclopentadiene (THDCPD) is a crucial reaction step to obtain JP-10. Raney Ni is currently the predominant hydrogenation catalyst utilized in industrial production, demonstrating remarkable efficiency in converting DCPD to THDCPD with yields surpassing 96%. − Nevertheless, this catalyst is susceptible to deactivation and lacks the ability to be recycled for multiple applications. Furthermore, alternative catalytic materials predominantly consist of noble metals, − posing cost-related challenges.…”

Defective metal−organic frameworks (MOFs) have shown great potential for catalysis due to abundant active sites and adjustable physical and chemical properties. A series of Ce-based MOFs with different defect contents were synthesized via a modulator-induced defect engineering strategy with the aid of the cell pulverization technique. The effects of modulators on the pore structure, morphology, valence distribution of Ce, and Lewis acidity of Ce-MOF-801 were systematically investigated. Among the different samples studied, the optimal Ce-MOF-801-50eq sample exhibited remarkable catalytic activity for DCPD hydrogenation, achieving a conversion rate of 100%, which is significantly higher compared to other Ce-MOF-801-neq samples as well as the Zr-MOF-801-50eq and Hf-MOF-801-50eq samples. The enhanced catalytic performance of Ce-MOF-801-50eq can be attributed to advantages provided by defect engineering, such as the high specific surface area, proper pore size distribution, abundant unsaturated metal sites, and Ce 3+ /Ce 4+ atom ratio, which have been supported by various characterizations. This study provides important insights into the rational design of Ce-MOFs in the field of catalytic DCPD hydrogenation.
