英文摘要The exploration of non-noble metal catalysts for alkane dehydrogenation and their catalytic mechanisms is the priority in catalysis research. Here, we report a high-density coordinatively unsaturated Zn cation (Zn-cus) catalyst for the direct dehydrogenation (DDH) of ethylbenzene (EB) to styrene (ST). The catalyst demonstrated good catalytic performance (similar to 40% initial EB conversion rate and >98% ST selectivity) and excellent regeneration ability in the reaction, which is attributed to the high-density (HD) distribution and high-stability structure of Zn-cus active sites on the surface of zinc silicate (HD-Zn-cus@ZS). Density functional theory (DFT) calculations further illustrated the reaction pathway and intermediates, supporting that the Zn-cus sites can efficiently activate the C-H bond of ethyl on ethylbenzene. Developing the high-density Zn-cus catalyst and exploring the catalytic mechanism laid a good foundation for designing practical non-noble metal catalysts.
