Abstract

Here we propose the emulsification of CO₂ and water with graphitic carbon nitride (g-C₃N₄), in which the g-C₃N₄-stabilized CO₂ droplets were utilized as “microreactors” for in situ photocatalytic CO₂ reduction. The g-C₃N₄ sheets assembling at the CO₂/water interface can serve both as an emulsifier and photocatalyst, which can greatly promote the conversion of CO₂ to formic acid.
