文摘

A heterogeneous catalyst made of well-defined Co₃O₄ hexagonal platelets with varied exposed facets is coupled with [Ru(bpy)₃]Cl₂ photosensitizers to effectively and efficiently reduce CO₂ under visible-light irradiation. Systematic investigation based on both experiment and theory discloses that the exposed {112} facets are crucial for activating CO₂ molecules, giving rise to significant enhancement of photocatalytic CO₂ reduction efficiency.
