Title: Surface modification of carbon black nanoparticles enhances photothermal separation and release of CO 2

Here, carbon black nanoparticles (CB) were covalently modified to improve the photothermal regeneration of a CO 2 capture nanofluid through decarboxylation. The photothermal release of CO 2 addresses high energy costs associated with regenerating capture fluids. By incorporating sulfonamides on the surface of CB, we enhance the photothermal separation of CO 2 from MEA by approximately 70% more than the unmodified CB. In contrast, with an anionic sulfonate on the surface, the total CO 2 released fell by approximately 60%. We verified the chemical composition and structure of surface modification using complementary techniques including FT-IR, TGA, XPS, and Raman spectroscopy.
