Photocatalytic CO 2 reduction (PCR) can release the issues of energy shortage and environmental pollution simultaneously. However, it is difficult to obtain satisfying PCR performance due to rapid carrier combination and limited light harvesting. Herein, facilitated charge transfer is achieved by building a Zn–O bridge at the interface of a hollow tandem heterojunction based on phthalocyanine. The optimized tandem heterojunction of molecular sulfonated cobalt phthalocyanine (CoSPc) and hollow TiO 2 @ZnIn 2 S 4 (H‐TiO 2 @ZIS/CoSPc) demonstrates the efficient photocatalytic generation of solar fuel, which is superior to pristine individual semiconductor catalysts and most reported relevant catalysts. Moreover, the hollow morphology of the heterojunction can elevate the photocatalytic performance by enhancing light absorption, exposing more active sites, and reducing the charge transfer distance. Specifically, efficient cascade charge transfer induced by the Zn–O bridge is verified by the experimental and theoretical results. The facile approach here holds great potential for designing highly efficient catalysts for solar fuel production.
