Photothermal carbon dioxide(CO2)methanation has attracted increasing interest in solar fuel synthesis,which employs the advantages of photocatalytic H2O splitting as a hydrogen source and photothermal catalytic CO2 reduction.This work prepared three-dimensional(3D)honeycomb N-doped carbon(NC)loaded with core-shell NiO@Ni nanoparticles generated in situ at 500 ℃(NiO@Ni/NC-500).Under the photothermal catalysis(200 ℃,1.5 W/cm2),the CH4 evolution rate of NiO@Ni/NC-500 reached 5.5 mmol/(g·h),which is much higher than that of the photocatalysis(0.8 mmol/(g·h))and the thermal catalysis(3.7 mmol/(g·h)).It is found that the generated localized surface plasmon resonance enhances the injection of hot electrons from Ni to NiO,while thermal heating accelerates the thermal motion of radicals,thus generating a strong photo-thermal synergistic effect on the reaction.The CO2 reduction to CH4 follows the*OCH pathway.This work demonstrates the synergistic effect of NiO@Ni and NC can enhance the catalytic performance of photothermal CO2 reduction reaction coupled with water splitting reaction.
