| 英文摘要 | The conversion of diluted CO2 into tunable syngas via photocatalysis is critical for implementing CO2 reduction practically, although the efficiency remains low. Herein, we report the use of graphene-modified transition metal hydroxides, namely, NiXCo1-X-GR, for the conversion of diluted CO2 into syngas with adjustable CO/H-2 ratios, utilizing Ru dyes as photosensitizers. The Ni(OH)(2)-GR cocatalyst can generate 12526 mu mol g(-1) h(-1) of CO and 844 mu mol g(-1) h(-1) of H-2, while the Co(OH)(2)-GR sample presents a generation rate of 2953 mu mol g(-1) h(-1) for CO and 10027 mu mol g(-1) h(-1) for H-2. Notably, by simply altering the addition amounts of nickel and cobalt in the transition metal composite, the CO/H-2 ratios in syngas can be easily regulated from 18:1 to 1:4. Experimental characterization of composites and DFT calculations suggest that the differing adsorption affinities of CO2 and H2O over Ni(OH)(2)-GR and Co(OH)(2)-GR play a significant role in determining the selectivity of CO and H-2 products, ultimately affecting the CO/H-2 ratios in syngas. Overall, these findings demonstrate the potential of graphene-modified transition metal hydroxides as efficient photocatalysts for CO2 reduction and syngas production. |
