Abstract The photocatalytic transformation of carbon dioxide (CO 2 ) into carbon‐based fuels or chemicals using sustainable solar energy is considered an ideal strategy for simultaneously alleviating the shortage and environmental crises. However, owing to low utilization sunlight inferior catalytic activity, conversion efficiency CO photoreduction far from satisfactory. In this study, a MOF‐derived hollow bimetallic oxide nanomaterial prepared efficient . First, unique ZIF‐67‐on‐InOF‐1 heterostructure successfully obtained by growing secondary Co‐based ZIF‐67 onto initial InOF‐1 nanorods. corresponding counterpart has larger specific surface area after acid etching, oxidized H‐Co 3 O 4 /In material exhibits abundant heterogeneous interfaces that expose more active sites. band structure corresponds well with photosensitizer [Ru(bpy) ]Cl , which results in high yield 4828 ± 570 µmol h −1 g stable activity over consecutive six runs, demonstrating adequate performance. This study demonstrates rational design MOF‐on‐MOF heterostructures can completely exploit synergistic effects between different components, may be extended other nanomaterials as promising catalysts practical storage.
