An artificial photosynthesis catalyst composed of CeO2, N-doped graphene and copper ions (CeO2-NG-Cu2+) was fabricated. The light-harvesting CeO2-NG was characterized by X-ray diffraction, transmission electron microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy. The photocatalytic reduction of CO2 was conducted in an aqueous solution of Na2SO3. Results indicated that the reduction rate of CO2 to methanol approached 507.3 mu mol . g(-1) cat . h(-1) for CeO2-NG-Cu2+ artificial photosynthesis system in 80 min, whereas the reduction rate was only 5.8 mu mol . g(-1) cat . h(-1) for bare CeO2-NG without metalloenzyme. Therefore, artificial metalloenzyme played a vital role in reducing CO2 to methanol fuel.
