Plasmon-mediated photothermal conversion by TiN nanocubes toward CO oxidation under solar light illumination

Titanium-nitride (TiN) nanocubes were decorated with platinum nanoparticles via a wet-chemistry route to yield TiN-supported Pt catalysts (Pt/TiN). Under illumination of the sunlight, the Pt/TiN catalyst exhibited 100-fold higher activity than SiO2-supported Pt catalysts toward the remediation of carbon monoxide (CO) due to plasmon-mediated photothermal conversion by the TiN nanocubes.
