## Abstract

We demonstrate the rational design and construction of sandwich-like ZnIn 2 S 4 –In 2 O 3 hierarchical tubular heterostructures by growing ZnIn 2 S 4 nanosheets on both inner and outer surfaces of In 2 O 3 microtubes as photocatalysts for efficient CO 2 photoreduction. The unique design integrates In 2 O 3 and ZnIn 2 S 4 into hierarchical one-dimensional (1D) open architectures with double-heterojunction shells and ultrathin two-dimensional (2D) nanosheet subunits. This design accelerates the separation and transfer of photogenerated charges, offers large surface area for CO 2 adsorption, and exposes abundant active sites for surface catalysis. Benefiting from the structural and compositional merits, the optimized ZnIn 2 S 4 –In 2 O 3 photocatalyst exhibits outstanding performance for reductive CO 2 deoxygenation with considerable CO generation rate (3075 μmol h –1 g –1 ) and high stability.
