A heterogeneous catalyst made of well‐defined Co 3 O 4 hexagonal platelets with varied exposed facets is coupled with [Ru(bpy) 3 ]Cl 2 photosensitizers to effectively and efficiently reduce CO 2 under visible‐light irradiation. Systematic investigation based on both experiment and theory discloses that the exposed {112} facets are crucial for activating CO 2 molecules, giving rise to significant enhancement of photocatalytic CO 2 reduction efficiency.
