Nickel–Sodalite: An Efficient Catalyst for Selective Hydrogenation of Dicyclopentadiene
In the current study, the hydrogenation of dicyclopentadiene (DCPD) to endo-tetrahydrodicyclopentadiene (endo-THDCPD) is performed using a sodalite-supported nickel (Ni–SOD) catalyst. The synthesized catalyst was characterized using various characterization techniques including temperature-programmed reduction (TPR), ammonia temperature-programmed desorption (NH3-TPD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder X-ray diffraction (PXRD), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), and Fourier-transform infrared spectroscopy (FT-IR). The total acidity as determined via TPD and Ni crystallite size as determined via PXRD were 0.22 mmol/gcat and 7.8 nm, respectively. The reaction parameters were optimized using the Ni–SOD catalyst (4 wt% Ni) for the hydrogenation of DCPD. A low Ni content of 4 wt% was required to achieve complete conversion and >99% selectivity. The optimized reaction parameters were 90 °C, 10 bar hydrogen pressure, 800 RPM stirring rate, catalyst: feed ratio of 0.1, and 6 h reaction time. This is the first report of the low-temperature activity of the Ni catalyst under solvent-free conditions, which removes all the possibility of side reactions such as retro-Diels–Alder reaction (RDAR). The yield of the hydrogenation reaction product, endo-THDCPD, was 99.5% using the Ni–SOD catalyst.
