Abstract
En 中文
Photothermal catalytic methanation of carbon dioxide (CO2) is a promising and sustainable method for carbon resource utilization. The efficiency of this process hinges on enhancing the photothermal conversion capacity and precisely designing the catalytically active sites. Here, a laser synthesis strategy is proposed to construct the RuO2/Fe2O3 heterostructure by laser etching to build a grooved Fe2O3 substrate and depositing RuO2 nanoparticles. RuO2/Fe2O3 combines the wide-spectrum absorption capacity of Fe2O3 substrates (reaching 209.2 °C under light irradiation with a light intensity of 1.83 W cm−2) and the catalytic activity of RuO2, enabling CO2 to have the ability of selective hydrogenation. Combined with the catalyst characterization and the catalytic experimental results, RuO2/Fe2O3 is confirmed to be a photothermal catalyst with excellent catalytic performance and stability for CO2 methanation (CH4 selectivity and yield are 96% and 795 µmol cm−2 h−1, respectively). This work provides a versatile platform for designing multi-functional catalytic systems by laser-assisted strategy, opening new avenues for solar-driven CO2 valorization.
