Endothermic reaction at room temperature enabled by deep-ultraviolet plasmons

Sequestration and conversion of CO2 is a promising method for remedying climate change. However, current technologies remain limited due to infeasible system demands and outputs, such as high-temperature/pressure conditions, use of precious metals, or low turnover efficiencies. Herein, we propose the conversion of CO2 ¬¬and C into CO at room temperature in the presence of earth-abundant Al. By directly utilizing the localized surface plasmon (LSP) resonance, we show that carbon gasification occurs near the Al nanoparticle surface under low CO2 pressure. An environmental transmission electron microscope is used to visualize and quantify the plasmonicly induced endothermic reaction at nanoscale. Our findings provide a low cost approach for CO2 reduction which promises large scale implementation and paves the ways to study other LSP induced endothermic reactions.
