摘要
利用太阳能将二氧化碳转化为富含能源的燃料和高价值化学品,是减轻对化石燃料依赖的可持续解决方案之一,但要达到所需的转化效率和对甲醇等产品的选择性仍具有挑战性。在这里,我们展示了用等离子金纳米粒子装饰的 In2O3 纳米线,它在光热 CO2 加氢制甲醇方面具有更高的活性。在光照射下,金纳米粒子诱导的局部表面等离子体共振缓解了甲醇合成的热力学限制。因此,与纯热催化过程相比,甲醇生产率大幅提高(320 μmol-g-1-h-1),同时甲醇选择性也得到显著改善。这项研究深入探讨了利用等离子纳米粒子通过光的利用来改进热催化的益处。
Photothermal catalytic CO2 hydrogenation to methanol on Au/In2O3 nanowires
Converting CO2 into energy-rich fuels and high-value chemicals using solar energy is one of the sustainable solutions to mitigate reliance on fossil fuels, yet attaining the required conversion efficiency and selectivity to products such as methanol remains challenging. Here, we present In2O3 nanowires decorated with plasmonic Au nanoparticles with improved activity for photothermal CO2 hydrogenation to methanol. Under light irradiation, the localized surface plasmon resonance induced by the Au nanoparticles alleviates the thermodynamic constraints of methanol synthesis. This results in a significant increase in methanol production rate (320 μmol·g−1·h−1) alongside meaningful improvement in methanol selectivity compared with the purely thermal catalytic process. This work provides insights into the benefits of harnessing plasmonic nanoparticles to improve upon thermocatalysis via light utilization.
