Coupling Direct Atmospheric CO 2 Capture with Photocatalytic CO 2 Reduction for Highly Efficient C 2 H 6 Production

As massive amounts of carbon dioxide (CO ) have been emitted into the atmosphere causing severe global warming problems, developing carbon-negative techniques to control atmospheric CO concentrations is enormously urgent. Herein, by coupling the direct atmosphere CO capture adsorbent ZSM-5 with the CO reduction photocatalyst NiV Se , we present the first synergistic approach for concentrating and converting atmospheric CO into C solar fuels. A C H yield of 1.85 μmol g h has been achieved in the air, outperforming state-of-the-art direct atmospheric CO conversion photocatalysts. Comprehensive characterizations show that ZSM-5 enhances CO capture from the atmosphere, improving the interfacial interaction of CO on the NiV Se surface for C-C coupling of CH * to form C H . This work demonstrates the first example of integrating direct CO capture material with a CO reduction photocatalyst for atmospheric CO capture and utilization, which paves the way for the negative-carbon technology development under worldwide carbon-neutral pressure.
