In this study, a novel twin reactor was developed to hydrogenate CO 2 into hydrocarbons by using H 2 directly produced from photocatalytic water splitting. The twin reactor was further modified to simultaneously perform the CO 2 hydrogenation and water splitting reactions in the gas and liquid phases, respectively. Moreover, two photocatalysts, Pt/TiO 2 and Cu/TiO 2 , were used to improve the photo-hydrogenation performance in the reactor. The results indicate that the H 2 produced from water splitting effectively enhanced the CO 2 hydrogenation in the gas phase, and we found that the highest CO 2 reduction activity was achieved by using Pt/TiO 2 and Cu/TiO 2 as the H 2 -generating and CO 2 hydrogenation photocatalysts, respectively, which promoted H 2 evolution and CO 2 hydrogenation and resulted in enhanced CO 2 photoreduction. ? 2018 Elsevier Ltd |
