| 英文摘要 | Rational design of efficient ethylbenzene (EB) dehydrogenation catalyst and reaction route is the key scientific challenge for styrene (ST) formation. We reported here a dual-path dehydrogenation (DPDH) route to efficiently convert EB to ST on a Pd/hollow nanocarbon spheres bifunctional catalyst, which exhibited ST formation rate up to 7.11 mmol g-1 h-1 with > 99 % selectivity. Detailed kinetic, isotopic and surface reaction analysis and corresponding DFT calculation suggested that the relatively high intrinsic catalytic activity originated not only from the single atomically dispersed Pd-based coordination structure but also the unique oxidative dehydroge-nation (ODH) assisted direct dehydrogenation (DDH) reaction route. In this route, the small amount of H2O produced from ODH effectively lowered the energy barrier for hydrogen generation/desorption via a proton transfer process promoting the DDH process. The present work shed light on the rational design of catalyst and routes for highly efficient alkane dehydrogenation reaction systems. |
