Solar Thermoplasmonic Nanofurnace for High-Temperature Heterogeneous Catalysis
Original language description
Most of existing solar thermal technologies require highly concentrated solar power to operate in the temperature range 300-600 degrees C. Here, thin films of refractory plasmonic TiN cylindrical nanocavities manufactured via flexible and scalable process are presented. The fabricated TiN films show polarization-insensitive 95% broadband absorption in the visible and near-infrared spectral ranges and act as plasmonic "nanofurnaces" capable of reaching temperatures above 600 degrees C under moderately concentrated solar irradiation (similar to 20 Suns). The demonstrated structures can be used to control nanometer-scale chemistry with zeptoliter (10(-21 )L) volumetric precision, catalyzing C-C bond formation and melting inorganic deposits. Also shown is the possibility to perform solar thermal CO oxidation at rates of 16 mol h(-1) m(-)2 and with a solar-to-heat thermoplasmonic efficiency of 63%. Access to scalable, cost-effective refractory plasmonic nanofurnaces opens the way to the development of modular solar thermal devices for sustainable catalytic processes.
