摘要：Photothermal catalysis of CO2 hydrogenation holds great potential in achieving carbon neutrality. However, the rational design of cost-effective photothermal catalysts with high performance for CO2 hydrogenation is an ongoing challenge. Herein, we employed CuCoyBOx composite catalysts by incorporating both CuBOx and amorphous CoBOx to efficiently catalyze the CO2 hydrogenation. Besides the high selectivity (98.0%), the optimized CuCo5BOx demonstrated a remarkable CO yield of 124.7 mmol g(-1) h(-1) under illumination at 300 degrees C, which was 3 times higher than the traditional thermocatalysis. Experimental results and theoretical calculations demonstrated CuBOx acted as a photocatalyst, donating electrons to CoBOx active sites. Coupling boron-oxygen species with CuCo bimetallic-oxides synergically enhanced the CO2 adsorption capacity and accelerated charge transfer, thereby enhancing the photothermal synergistic effect and consequently boosting the catalytic activity. This study establishes an approach for the rational design of non-precious metal-boride catalysts, enabling efficient photothermal conversion of CO2 into CO under mild conditions.
