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.

Converting renewable biomass and their derivatives into chemicals and fuels has received much attention to reduce the dependence on fossil resources. Photocatalytic ethanol dehydrogenation–acetalization to prepare value‐added 1,1‐diethoxyethane and H2 was achieved over non‐precious metal CdS/Ni‐MoS2 catalyst under visible light. The system displays an excellent production rate and high selectivity of 1,1‐diethoxyethane, 52.1 mmol g−1 h−1 and 99.2 %, respectively. In‐situ electron spin resonance, photoluminescence spectroscopy and transient photocurrent responses were conducted to investigate the mechanism. This study provides a promising strategy for a green application of bioethanol.
