CO 2 hydrogenation to gasoline fuels remains a sticky problem of CO selectivity from reverse water-gas shift reactions over a metal oxide and zeolite bifunctional catalyst. Herein, we report an efficient catalyst combining a Fe−Zn−Zr−T oxide hydrothermally treated with TPABr solution and HZSM-5 zeolite for CO 2 hydrogenation into high-quality gasoline. The hydrothermal treatment contributes to the obvious enrichment of the Zn component and the residual Br on the surface of Fe−Zn− Zr−T oxide, as compared to Fe−Zn−Zr oxide, as well as the increased number of oxygen vacancies. These surface properties not only induce the increase of the H 2 adsorption and CO 2 adsorption ratio but also enhance the adsorption strength of the HCOO* species and the desorption rate of CH 3 O* species (close intermediate of methanol) over Fe−Zn−Zr−T oxide, which are responsible for higher methanol selectivity and lower CO selectivity. Furthermore, the presence of the adsorbed CO* species and higher C 2+ hydrocarbon selectivity on Fe−Zn−Zr oxide affirm the F−T route of CO 2 hydrogenation except for the methanol route, while the F−T route is effectively restrained after the TPABr hydrothermal treatment of Fe−Zn−Zr−T oxide. As the Fe and Zn−Zr molar ratio decreases, more HCOO* and CH 3 O* species on Fe−Zn−Zr (0.1:1:1)−T−24 h can form, which is in good agreement with the much higher methanol selectivity on Fe−Zn−Zr (0.1:1:1)−T−24 h oxide and hydrocarbon selectivity on the Fe−Zn− Zr(0.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
