Considering the relative high amount of carbon atoms in jet fuel, the selective regulation of C-C coupling is challenging, so the direct synthesis of jet fuel components from CO2 hydrogenation is rarely reported . With respect to this problem, researchers put forward the concept of "cascade catalysis", which coupling two or multiple reactions to improve the selectivity of target products by modulating the composition, property, content, spatial position of catalysts . For example, Yuan et al employed CO2 and H2 replacing methanol in toluene alkylation over ZnZrOx-ZSM-5 dual-functional catalysts for the selective synthesis of xylene . During the reaction, the reactive methylation species are generated from ZZO by CO2 hydrogenation and migrated to the pore structure of Z5 methylating toluene to xylene, giving 92.4% xylene selectivity in CO-free products and 70.8% para-xylene selectivity in xylene over the optimized catalyst higher than the methanol route . Pan et al observed that when the external acid sites of ZSM-5 were shielded by silica, the formation of para-xylene were significantly enhanced . During these catalytic processes, C1 oxygen containing compounds formed on the metal oxide, which diffuse quickly to the acid sites of zeolite for the further methylation reaction with the para-xylene selectively formed owing to the sieving effects of the pores in ZSM-5. While the carbon utilization efficiency was restricted by the insufficient H2 dissociation ability of metal oxide (i.e. ZnZrOx, ZnCrOx) and high byproduct CO selectivity .
