由具有不同暴露面的明确定义的Co 3 O 4六方片晶制成的非均相催化剂与[Ru（bpy）（3）]Cl-2光敏剂偶联，以在可见光照射下有效且高效地还原CO2。基于实验和理论的系统研究表明，暴露的{112}面是活化CO2分子的关键，从而显著提高光催化CO2还原效率。
A heterogeneous catalyst made of well-defined Co3O4 hexagonal platelets with varied exposed facets is coupled with [Ru(bpy)(3)]Cl-2 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.
