Making full use of photogenerated charge carriers by careful design multifunctional photocatalysts to achieving bi-value-added production with high-efficiency is highly desirable and extremely challenge. Herein, a novel 2D/3D ZnIn 2 S 4 @Ni 1 /UiO-66-NH 2 (ZIS@Ni 1 /UN) heterojunction with spatially separated and precise redox sites was designed and fabricated for both photocatalytic H 2 production and benzyl alcohol (BA) valorization. By precise structural regulation and modification of UiO-66 integrated with -NH 2 , ZnIn 2 S 4 (ZIS) and Ni single-atom, the spatial separation of redox sites and directional electron transfer has been achieved. This realizes collaborative and efficient solar energy to chemical energy conversion. The optimal sample 5ZIS@Ni 1 /UN-6 shows high photocatalytic H 2 and benzaldehyde (BAD) production rates of 11.44 mmol∙g−1∙h−1 and 10.02 mmol∙g−1∙h−1 under visible light. This work highlights the importance of rational construction for the engineering of charge behavior in heterogeneous photocatalysts with spatial separation and identifies their crucial role in promoting the photocatalytic redox coupling reactions. [Display omitted] • A novel 2D/3D ZnIn 2 S 4 @Ni 1 /UiO-66-NH 2 heterojunction is successfully design and fabricated. • High production rates of benzaldehyde and H 2 simultaneous is achieved under visible-light. • Precise construction of spatially separated redox-sites and directional electron transfer synergistically boost photocatalytic performance. • The carbon-centered free radical process of selective oxidation of benzylalcohol is confirmed by in-situ EPR.
